As I said any xanim could be the cause of the issue or virtually anything that was recently added/edited.

what do you suggest then? I have tried re installing my game and modtools and patches/updates and no luck

From what I gathered it's failing on actually compiling xanim's try reverting whatever anim you edited recently.

I've never edited any. I've done a fresh install of the tools and the game and still no hope. I have piemans five teleporters installed and harrybo2s perks and some mw2,3 and black ops 1,2 weapons. Could these be a problem?

Use this application to see where it fails to compile.

How-to:
Run Dbgview.exe
Compile mod
Look at Dbgview to see which asset it fails on.

I used the tool and it fails on this "adding char_usa_marine_polonsky_zomb". What does it mean?

Well i can buy the perks now but the machines are invisible. I think I know the problem though. Thanks for your help.

How did you fix it. I have been stuck on this for a while. I also have another error saying can't find vulture.pap. any help would be appreciated.
