When I first added the PV4 capability to ADE-GP, it seemed possible to use FSX materials not only with PV3/4 but also FSX GPs. Unfortunately, the implementation of that capability left something to be desired, since FSX has been known to freeze when encountering GP files with this capability.
ADE-GP 2.2.08 deletes this feature and reverts to simple FS8-style GPs for both FS9 and FSX (and SE, Pv1 and Pv2).
This change does not affect generation of GPs for P3D v3/4.
If you use ADE 1.75 or later to develop FSX airports containing ground polys, please ensure you are using ADE-GP 2.2.08 with it. (The ADE-GP version number is contained in the title bar of the GP Editor or can be determined with Windows Properties.)
For your convenience, the v2.2.08 .dll is attached. Simply copy it into your ADE folder if you need it. If your system complains of missing files, the full release is available from
http://stuff4fs.com. Navigate to the User applications/ADE Ground Polys page.
Sorry about that, folks. My intentions were true.

EDIT: There's still an issue in 2.2.08. I believe it to be fixed in 2.2.09, currently being verified. Please do not install 2.2.08.
