Pull up your system setting and disable your internet connection. Then set your date to the current date & time. Then reboot your system and everything should work fine but you won't have internet access. This should bypass your error pulling up trophies. I haven't been able to test it yet since I left my house and am at my gfs

found the link he got it from, works for some, not for others.

No luck. I can navigate through the menus on MW2 but eventually the trophy screen comes up and I have to close. Can get as far as loading a mission up lol.
