Game crushes while co-op entering.

Your problem caused by 32-bit OS memory limitations:

Code:

   Operating System: Windows 7 Ïðîôåññèîíàëüíàÿ 32-bit (6.1, Build 7601) Service Pack 1 (7601.win7sp1_gdr.140303-2144)
             Memory: 4096MB RAM
Available OS Memory: 3328MB RAM

Also your drivers really old and this will cause crashes too:

Code:

          Card name: NVIDIA GeForce 9600 GT
   Driver Date/Size: 2/26/2013 00:22:30, 15129960 bytes

You need download and install latest drivers from Nvidia website:
