Fixes

[R@S]

I assume you're using Win 7 and here's what you do:
Search your drives for files called *.azp and see what folders contain such files.

I think it's \AppData\Local\VirtualStore\Program Files, but not sure. Delete all *.azp and *.TGA files in that 7.62 directory located there(not your install game directory). This should fix your problems.

Be sure that you set all TGA files to read-only in your BMP\HUD\ sub folders before you start a game, set the files, not folders.

I hope this helps, if not, please post more info on your problem, such as your log located in the \7.62\log\ folder.

Good luck

EDIT: Please use the Unofficial Patch, then all you have to fix yourself is setting the files to read-only
