You're welcome, Dane.
BTW: In addition to the links I posted above, I am suggesting that if you have not done so already, be sure to view these pages:
http://www.fsd-international.com/Hangar/V35B/
http://www.fsd-international.com/support/guarantee.htm
NOTE: In the latter link, you may wish to review certain statements in particular (quoted for purposes of review):
Refund requests must be made within 10 days of date of purchase.
The version of Flight Simulator for which the software is compatible is clearly specified for every title. Returns due to version incompatibility will be subject to a $4.00 non-recoverable license fee.
Refunds due to duplicate orders or orders by mistake are also subject to a $4.00 non-recoverable license fee.
The software must be completely uninstalled on each computer on which it was installed prior to receiving a refund.
An uninstall tool will be provided for this purpose. If the purchase was by CD-ROM, the CD must be returned as well.
Shipping charges from the original purchase, and for return of the disk, are not refundable.
If a refund is requested due to technical issues we request that a good faith effort be made to follow the suggestions from our technical support staff first. For example, like a lot of Windows software, restrictive Windows access are permissions issues can result in installations problems. Software (not just ours) often requires no permissions restrictions, and sometimes, temporarily disabling security software. We have a publication that details this issue here. We cannot honor a refund request if you do not follow these procedures.
Unconventional hardware setups can create difficulties within the complex security environment in todays operating systems. For example, running programs like Flight Simulator or Prepar3D on external drives, SSD drives, etc. Windows is hostile to these locations on your computer in terms of access/permissions issues. We will work with you to try and resolve these Windows security related issues, but cannot guarantee that these unconventional setups will work. Refunds due to such Windows security issues or unconventional hardware setups will be subject to a $4.00 non-recoverable license fee.
CAVEAT: It is apparent that you have at some point 'customized' the panel configuration for a FSD payware aircraft.
Be aware that FSD gauges are very sophisticated, and have interconnections with various locations on your hard drive as well as in the Windows registry, and altering any of that out-of-the box default functionality as intended by FSD may at the least cause malfunction, and perhaps even void their terms and conditions for support or refund eligibility.
Also, since it would not be a default configuration when one has tinkered with their panel and/or gauge file configuration, it is not an impossibility that FSD will refuse to support your re-installation or removal of that aircraft and/or any of their add-on gauges.
Additionally, be aware that public discussions on various FS web forums contain numerous reports that FSD, in spite of the technical brilliance of their original in-house and sub-contracted design team(s) with nearly all products over the years, have a IMHO, appalling history for how they treat their customers even when all their instructions and install / un-install utility procedures have been followed precisely.
Personally, as a former customer of theirs, I decided not to give them further business because of their, IMHO, bad behavior by initially accusing me of piracy because purportedly their <
not-so-foolproof ? > software "should" have otherwise worked properly.
It turned out that they had failed to disclose "Shockwave Flash" had to be enabled throughout my Windows and web browser configurations in order for their store / download / install / configuration / un-install software to all work properly, and at that time I had inadvertently disabled "Flash" everywhere on my computer via a particularly 'over-zealous' plugin extension to FireFox.
In your OP for this thread, you have indicated you would like to customize the panel and gauge configuration for the FSD Beechcraft V-Tail Bonanza to utilize non-FSD panel and gauge components.
I am doubtful that anyone here at fsdeveloper forums would be willing to assist with circumventing the intended design and security measures built into a payware aircraft, especially one from FSD.
And I
doubt am confident that FSD would
NOT support that process either.
AFAIK, there are other Beechcraft V-Tail Bonanza aircraft available as both payware and freeware; I suggest that you consider those options.
I would also suggest that you re-consider how your present dilemma with the DLL.XML file and the panel and gauge configuration for the FSD Beechcraft V-Tail Bonanza ...may have originally occurred.
It also seems possible that the FSD install / un-install may have failed due to your having some configuration issues in Windows with security and/or file / folder permissions that the FSD software may not be able to deal with successfully.
Alternatively, you may have had unexpected issues with the panel and/or gauge configuration of the aircraft at the time you attempted to un-install it ...that the FSD software may not be able to deal with successfully.
As for me, I continue to await the Aerosoft Pilatus PC-6 Porter ..to replace my FSD version of that aircraft (the FSX version was re-
port-edly a "
port" of the FS9
Porter model ...despite the 'upgrade' fee
). 
Good luck with your endeavors.
