I am unable to use the Playstation Plus 1-month membership that came with God of War Saga. When I enter the key on my account it works but does nothing. After doing some research it seems the voucher code is for a trial and will not work for someone who has already payed for Playstation Plus in the past (ultra lame).
Anyways, my problem is i gave this voucher to a friend of mine who has never been subscribed to Plus and it tells him the code is invalid. Since i couldnt use this code on my account can you fix the problem with the code turning invalid because it was used in a way that didnt work?
