Everything is running fine now. I did get an error when I first started up but I replaced the BGLMANX..DLL as you had listed here and that fixed the problem. I also did a clean install of GSX per your instructions and it's working but after a few minutes I get the following error.

The error does not crash the sim. Framerates are incredible.
