I own two games on my new psp go, GT PSP and rock band unplugged (which came with it). Now i signed into my regular psn account with it and downloaded my free rockband unplugged. however when i went to buy GT PSP i had to use my other account because it has the credit card information and the proper region for the credit card (my other account is american and me being canadian wont let me use my credit card.) so now i can only play one of my two games unless im at a wifi access point to switch accounts, and then i cant play the other. any options for me?
