Hi guys,
I've just bought The Binding of Isaac in a shop, and they told me it wasn't tradable yet.
I've still made the trade and when I accepted, the bot sent me an offer with the game.
So I've accepted but I can't add it to my library.
So if anyone can help, that's really bother me.

Ok so I had to sent it to a friend who sented it back and then I could, Steam bug probably, subject closed :)
