It's possible to have more then one cheat software - however - this process takes up alot of memory.
So to get around this - only have one of them activated at any giving time.
If you have multiple plugins - disable the ones that are non-game related for best results.

I currently have CW2.2B and NitePR revK - I plan ahead / meaning if I'm going to through down with Combat Ops - I would enable NitePR, but If I were to through down on God of Wars or what not, then I would enable CW.

This process has worked great and doesn't cause much hassle to do with the VSH menu.
