Ok, so I bought STEAM's Crysis Collection, which includes STEAM Crysis 2 Maximum Edition.

The STEAM C2ME game works properly... SP and MP no problem. I am having a bit of trouble with the Crysis 2 Coop Mod (http://www.moddb.com/mods/crysis-2-co-op/downloads). I have it installed and I can load it via the provided Launcher.exe or the Crysis 2 Main Menu.

However, when I go to start a Coop Campaign the box where the map list is blank and I can not start a self server either. So how do I know if it is working correctly?

Any help would be greatly appreciated
