I have recently tried to add Black Ops perks into my map. I did everything according to the tutorial, but I have one small problem. Every time I'm trying to run my map I'm getting this error:

It's kind of hard for me to belive that my computer wouldn't be able to handle 4 more perks...
By deleting each file one by one I finally managed to find which one is causing the problem. If i delete the 'nazi_zombie_MAPNAME_patch.ff that i got from downloading the files from the tutorial the map works fine except that i'm missing the models of the perk machines and I dont see animations when he is suppoust to drink from the bottle. Instead of it the perk starts working after like half a minute and before it works i cant run or zoom in.
As I said the patch file is making my game crush, if i overwrite it with my own patch file it works 50% of how it's suppoust to. Does anyone know how to fix it? Any help really appreciate, since I'm trying to fix it since yesterday
