Before the forums crashed, someone had a problem where when they entered their name to fly a campaign, CFS claimed it was already in use. Yesterday I solved that problem.
I accidentaly deleted the campaign folder. So when I went to fly a campaign my name didn't show on the list. When I re-entered my name, the game said that my name was already used. So I recopied the campaigns folder from the CD and tried again. Everything worked.
PS. It's a shame that everything on the forums got erased. But at least our new posts are staying put!
