I got the game again, anyway, i tried getting online, (which it worked 3rd time) and iv noticed a bug. every time i go on 'find game' my psp crashes and then, 10 seconds later, my psp turned itself off. any solutions from anyone?

Is the UMD scratched or in any other way damaged?

no. its not scratched, but i got the game yesterday, how can it be scratched?

It might have been preowned?

Yes, your right. i dicided to get a cheaper version of it, so it must be preowned. Stupid people dont know how to treat UMDs do they?
