Custom Map Crashing - Will Recieve reward if you help

[Thegreen16]

Everytime I try a map other than the demo maps, I crash or go back to the main menu. I've tried extracting all the files, the models/materials etc. It doesn't work! I've also tried installing it 4 times.

I get this in console before I crash

Any Ideas? I've installed the lastest drivers, tried different maps, defragmented my pc.

Ummmm, what you wanna do is load up an official map in singleplayer. Then open console and type in "changelevel mapname"

That should work. If you did that, then iono.

Is it a map you compiled or did you get it in bsp form?
