Hey, I'm having a problem... I have the resistance cso on my psp, the game works fine. I had a ripped version a while back (multiplayer only). But I decided to get me the full game... I tried going on multiplayer.. but it wouldn't work. I haven't played resistance in forever so I don't know if anythings been going on with the game or its just me... but it used to work when I had 5.00 M33-6. I downgraded to 4.01 M33-2.

Is it because I have a older firmware? (I'm aware of the PS Store being blocked from CFW accessing it)
