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

Why u want 5 man?
Oh ya caz you noob so you can't join other ppl room
Doesnt really matter caz they kick you in game so they become host

Not shure if its been patched, dont really think so.

Wait, what? The reason I want to make my own room is because only the higher ranks know how, and they always kick me out of the room when I join T_T.
