I keep getting memory access violations when playing Dead Ops Arcade. I just made it to the end of round 2 when I entered the area for round 3, when the game gave me the memory access violation notice.

I wanted to use console commands such as godmode and such, but it keeps saying "Cheats are not enabled on this server" even if I use /devmap or /spdevmap. The reason why I want to use console commands is just for fun and seeing every weapon available in the mod itself.
