As of last night, I lost all my perk levels. I tried restarting steam, verifying game cache and all that. I wasn't to worried because it worked once, however this time it didn't work... I thought it was because Steam was down and what not, but the five other people I was playing with had no such problem. I shut down my computer for the night, and when I tried to play again today, I still have that problem. It took me a while to level up and I am really not willing to do it again.

Any help would be greatly appreciated
