I don't know if this helps your goals any, but you could just delete the .wine folder (in your home folder) and start over. That will at least get you back to single-player. Save anything you want to save first. As far as how to get multiplayer to work, I don't know. You could always try installing to Windows and copying the files and registry keys over. RegShot and WhatChanged can assist with this. Cheers, Jake
