So I downloaded the mod yesterday. Immediately I notice immense lag upon entering one of the maps (i forget the name but its the one with the russians and germans in the woods) And then any server I get on I play a max of one game and crash to desktop on the next map. What is this? is it

1. A ping issue: I have been kicked before for High ping
2. a Pc issue: I have a 512 gb card, 3.2 P4 and 4gigs of ram

Any help on this would be greatly appreciated.

Edit: I got an error box during one of my crashes:

memory.dll: all alloc attempts failed for size 1261421. I saw that this happens alot with vista users but im running on XP
