Lost Money/Stats/Tags/Rating/Unlocked Customs

Played the free weekend, everything worked fine. Bought the game and lost everything. Money, stats, tags, unlocked customs...all of it. Now when I play the game doesn't save any of my new stuff either. Anyone else with this issue?

EDIT: I am now getting an error message "Failed to unlock achievement. Please check storage device." when I unlock and achievement in game.

this happened to me last night, shut mnc off for about 45 min when i tried to play i had been robbed! $0 cash on hand with a little under 2 mil lifetime no custom classes either! I bet it was those blackjacks i saw on the corner the other day! please help! ive reinstalled on steam and when i check for file consistency it says 1 file failed to validate and will be reacquired... but then i check again with the same result. I reinstall with the same result too...

Ive just finished removing all traces of steam from my computer including the registry, restarted then reinstalled steam and mnc... $0 still... and 1 file still fails to validate every time i scan...
