After almost 2 days of play, i went to turn in a minute man quest, and as he did the usual "I have other work - go do blah blah blah" I sat there waiting for the quest to start, but i was met with nothing. The quest never started. Thinking it was just a bugged quest i went and tried to start a different quest, to no avail. I now cannot start any quest, but i can finish older ones, leaving me with an unplayable game, and alot of wasted time. I also discovered that i cannot barter with any traders because both my inventory, and theirs, are totaly blank. I contacted the support team and got the usual - sorry cant help, bye. So that didn't help. Now i turn to you guys, so do your best, and please tell me i dont have to restart my character...

Any mods?

you could try to repair the game.

in steam there is a 'verify game cache' option under your game settings -> local files.

What's the exact quest you are in?
