few days ago i was surfing on net in psp and opened one web. My psp freezed nothing worked i couldnīt turn it off - simply nothing. after few minutes i turned it off by long holding off button and i turned it OFF (from my last update i could not turn it off, just sleep it so...) when i started it again everything was good but all games were gone (only Map this was there and all music vids or saved games were there) I connected it with PC and games were there but my psp could not read them or what. i tryed to put there some other game but it did not worked too so now i have no idea what to do next.
Thanks for all answers
