Wednesday (24th of February), I played Freelancer for about 1 hour. So, it worked.
Today (27th of February), I launch FL Launcher. File 11 and 30 are being downloaded, and I press START MULTIPLAYER BUTTON. After a few seconds of nothing-happening, I get a Send/Don't Send error (I think/hope you all know what that is). Same thing happens when I try to START SINGLEPLAYER.
What the hell?! What could it be? I did not modify anything in the Freelancer folder until now, and my AVG is kinda inactive, so I can't explain it. Unless... some powerful force such as Luke Skywalker's ghost energetically attacked me... or OP banned me somehow?
