"Exists in Your Account" BUG!!!

Have you tried syncing your account?

This is a known issue with free weekends. All that can be done is for the user to remove any game content they may have on their computer and resync their SteamGifts account. It can take up to two weeks for Steam to update the user's library to reflect they do not own the game, however. Sadly, this is a problem on Steam's end and we can't change it.

Same with me, with a resync. Natural Selection 2 and Ace Of Spades are counted for in my account, but it was for Free Weekend. I coudnt enter in the AOS giveaway with 3 copies. I could have won. :l

Just resync. this happened with me too with Ace of Spades.

Done... but why its so long taking? 10 minutes od sync? :(

Edit: This crap dont work... 10 minutes of sync and Im still got games from free weekend... booo!!! Gala Giveaway working better :/
