En als je een andere profiel kiest loopt hij dan ook vast? Probeer dit eens en lees het wel goed als je uw data wilt behouden. Als eerst zou ik Rebuild Database doen en als dit niet lukt Restore File System.
Go into recovery, and run the option Restore File System (and Rebuild Database). This option should NOT delete any of your data or save data, but just a way to fix corrupted files and the likes). Edit: I just read somewhere that one of these options might delete all your music playlists, if you have any, and maybe rename all of your music tracks to Track01 or something like that. I'm not sure, but if you don't have music, or it doesn't really matter, then there shouldn't be a problem.
To get into the recovery menu:
Turn off your PS3 completely until it is in Standby mode (red light)
Hold down the power button. The PS3 will turn on, and eventually turn off (standby) after a series of beeps
Hold down the power button again until you hear two fast beeps (it goes like this: beep. beep. then two-fast beeps. Release here.)
Once in the menu. Run the options I mentioned above (Restore File System). Once it's done, restart the PS3
If it still does not work, go into recovery again and run another option called Rebuild Database.
Be careful, do NOT choose any other options in the Recovery menu like RESTORE PS3 SYSTEM as this will delete everything on your PS3.
