Installed Model Converter X 1.1 yesterday. After installing, I went to FSDS 3.5.1 and selected a fsc file I had been working with. The files loaded up everything "except" the 3D view screen. I went to the Solid View Control to move the Zoom slider. When I start moving the slider, I get this message in a FSdesign 35 window: Direct X error (887602f8) Render Target Buffer lost. Unknown Direct X error. This is the very first time I have "ever" received such a message. I have XP home 32 bit SP3 operating system with 4 GB of ram. Today I reinstalled the latest version of Direct X and in the control panel Repaired FSDS. Same problem occurs. And, I still get a error message when I open Model Converter X. Have you encountered this problem before? Thank you for your time and appreciate any help.
