Hmm...

Never had that problem before, although i'am having problems logging in myself. After clicking accept on the user agreement, it tells me that i was caught cheating once and cannot login even though i didn't hack, i don't even have my NitePR enabled.

Strange thing was i got booted before that so im pretty sure some tard caused it. Maybe the same case for you, i don't know.

I deleted the 1.60 update on my psp and prolly try to delete SOCOM FTB2 and copy it back on my psp again to see if that'll fix my problem. Why won't you try that as well and see if it'll work for you.
