All of the sudden, I can't sign into PlayStation Network. I keep getting this message:

An error has occurred. You have been signed out of PlayStation Network (8001050F).

When I test my connection I get this:

Obtain IP Address: Succeeded
Internet Connection: Succeeded
PlayStation Network: Failed

And when I start MW2, without even trying to get online, I get this at the game's welcome screen:

Registration of the trophy information could not be completed. The game will quit. (8001050F)

Has anyone had this problem? I searched online but cannot seem to find an answer. The weird thing is I can still access the internet through the browser, just cannot get onto PSN.
