I installed the game twice using the gog downloader and I allways seem to get a missing texture its the uh underware like the area above the pants its just black ive tryed messing with settings but nothing helps.
- update drivers (even if you think you have)
- do you have any overrides or haks?
- what's your OS?
- running as admin?
- If on Win 7 (seems to be most problems there), try typical troubleshooting like XP mode, disabling desktop and graphics enhancements, etc.
I wouldn't bother downloading more times. I'm sure you've got everything you need.
If you can get screenshots, that may help. And any more info can help.
