I download some free add-ons for modnation racers under my username on my ps3 and then when i signed in under a different username on my ps3 they are not there. do i have to download them for each username in order to use them? what about add-ons that cost? I don't have to download them for each username do i? also my wallet has one amount and a sub account has a different amount. i thought the wallet gets shared by the funds in the master acct.
