Backstory:
I bought FS2 in 2001 or so, and absolutely loved it. Played it through, twice, beat it twice.
Then I lost my CDs (gave them to a friend who moved to a different country... that bastard)!
Then in 2003 I downloaded the HotU version, and played that through. Fun, but annoying because text just whipped by.
Then I finally found some FS2 ISOs online-which I assure you were perfectly legitimate!

-and played through the game, again. This was just last month or so. FS2 open with the media VPs made things pretty.
And then I got stupid and decided to try some multiplayer... and now I've managed to lose my SP pilot.
I can't convert him, I can't see the campaign missions in the tech room, clicking on "Continue campaign" just brings me back to the start of the campagin.
However I'd really like to explore some of the later missions, now that I have the new 3.6.5 media vps, and experience some of the missions that had groovy coloured lighting from the shinemaps.
So is there anyway to get that information back? Or unlock the campaign so I can play the later missions without having to go through the whole sequence... again? I even tried downloading the co-op files, but my game crashes on launching multiplayer anything.
So... can you help me out anyone?
