"The inventary of this Shop for at least one game that you have selected to pay is full, please try to pay with items of other games"
My Inventory says:
Inventory (0/10)
Team Fortress 2: 0/10, Portal 2: 0/10, DOTA 2: 0/10, Steam Gifts: 0/0, Trading Cards: 0/10, Coupons: 0/10, CS:GO: 0/10
Maybe the problem is on the "Steam Gifts" part.
