At first, thanks for your report about running a megamod with Vista.
ChVidImage3d.cpp at line 629 error
There are some reports in the forums about the same error.
1.) This sounds like a corrupted animation BAM file. Try clearing the \cache, \temp, and \tempsave folders, and try again.
2.) It could be a problem between the older BG and the newer hardware. So start bgconfig and change all to a minimum (e.g. 640x480) and off (sounds, etc.). Save it and try BG again.
Here you can see what google finds about the error:

Greetings Leomar
I just wanted to point out that the problem was that I was using a higher unsupported resolution. Turning it back to 800x600 fixed every problem. I guess it is because of the fixed textured mods that are created based on 800x600. Thank you regardless
