Co-op crash on startup

Aloha,
Trying to play co-op with some friends but the game crashes on startup. I have no problems in singleplayer. The fix in the FAQ doesn't work because I do not have "wolconfig.coop.cfg" in my "Documents/RealRTCWCoop/coopmain"
I have completely deleted every folder related to RealRTCW, uninstalled, reinstalled, to no avail. Scouring through these discussions hasn't helped either. I just updated my graphics driver too.
Mahalo!
