Hmm, this is very strange. I played a game earlier today, finished it and quit with no problem. Now, a few hours later I try running the game and I get a box right before the intro video would normally play. It says:

Brush State (Disabled) TexturePixelBox is not within the Texture's Dimensions.

Brush: EscapeMenuWindowOptionButtonSaveGame
TexturePixelBox: 238, 334, 355, 416
Texture: 0, 0, 0, 0

It gives me the option to Skip, Skip All or Break. No matter which one I click, it brings up another one of these errors.

Okay, I've been clicking on the Skip All button for a while now, and now it says that it cannot find Mesh C:\gs\main\DataSource\Mesh\TechDroid.mesh

After going through it some more, It shows that I'm missing some ogg files. Okay, I checked the sound folder and these are indeed not there. What would have caused these files to go missing. I never even touched the Sound folder today, but apparently a whole bunch of them seemed to have gone missing in the past three hours.

Well, I skipped all the error boxes, and naturally the game ended up crashing, which was to be expected. Now, I'll probably reinstall my game to fill in the files that appeared to have gone missing, but does anyone know what may have caused the files to go missing in the first place? The only thing that I've done since I played last is put a replay file in the recorded games folder in My Documents. First time I've done that, but I don't see how that could have caused some files to mysteriously vanish.
