AVA 5 player coop glitch help

So I go on cheat engine and when I try to select the process AVA.exe I get an error message that it cannot be selected. Am I picking the wrong process or has it been patched?

I am using win7 64 bit.

Bump, still unanswered and I posted on about 5 other threads in this section so I think I earned it
