psp and ps3 question?

hey sup fellas, have quick question for ya..... i have 2 psp and and i have a bunch of psp games and ps1 games, now one of the psp's has my id and the other my gf, now both psp's are registered on my PS3, but the thing is i cant seem to play the game on my gfs psp, says somethin like content cant be played or somethin on this account, wat do i have to do exactly? does it need my main id on both psps in order for me to use the games? i cant share the games with my gf without having her use my id? if anyone can help me out id be much appreciated thanks

just log onto your account from your girlfriends psp and you should be able to download them from you older purchases
