" Sorry, an error has occurred: Limit exceeded "

I've bought recently Payday 2 with tf2 keys, as a gift that I can add to my library, until now, it's ok. Then I tried to add it at my library, so, there was the problem " Sorry, an error has occurred:

Limit exceeded "

I was thinking that was cause I've made a recently purchase, that's was pending the payment, and I don't really intend to pay it, cause I already bought it, what can I do to activate my game? answear it as fastest as possible, please '-' ?
