One of your ini files in the Freelancer folder got overwritten (the one which tells the app where to find the master Disco server). I'm at work at the moment so I can't look up which one it is... One of the other resident tech gurus might help out. If not, it'll be another 7 hours before you'll have your answer.
Reinstalling the Freelancer mod should work too.
