Change your texture quality. Set it to medium or high. Don't set it to extra. That should fix your problem. Thats a T4M issue for some graphics cards.

Ya it worked when I turned off specular ...

I'm having the problem described here when I try to play: http://ugx-mods.com/forum/index.php?topic=9886.0
It also happens with Nuketown, but Ragnarok (which also uses T4M) works perfectly. Does anybody know how I can fix this?

Every time I try to play this map the whole game crashes on me.

You need to have T4M installed
