gift was revoked for some reason. as i asume it because of this section listed on steam...
Where is my gift, and why was it removed?
When a gift is refunded due to fraud or a payment dispute, the gift is removed from Steam. The account which redeemed the gift receives a notification that the game is no longer available to play in his or her Steam library.
Should be there now. Steam said they froze and locked my account because they thought it was hacked. But they unlocked it and it should be back in your account now
