Use of Ebay Gift card - doesn't work, says it is linked with another PP account

[#1]

Hi, I won a $25 Ebay Gift card on Listia. Now I used the code that was emailed to me, and it tells me that I can't use this code since it is tied to another PP account. Does that mean that the code is in that person's PP account and can't transfer the code to my PP account? Help!
