PS3 8001050F Error fix?

When i start MW2 I get this error
"Registration of the trophy information could not be completed"
"The game will end"
"8001050F"

Any help?

1 your in the wrong section.
2 you would have a better chance by going to the game fourms for help. Were a hacking site, we help with hacks mostly.
3 Google is your firend.

Too old, I got signed out of PSN while I was playing MW2. then 10minutes later it said PSN status changed and it went out of the game.

I was so fucking pissed when it signed me out I got fucking 23/0 and about to get a nuke then it told me that shit.
