Help!

I've got 2k12 for PS3 and I can't get online, it says I'm not signed in. I'm definitely signed in on the PS account, they must mean signed in to the 2k servers. How do I do this?

the 2K servers have been having issues (already, yea) so just try again later.

Cool, I thought I had to enter a redeem code like with Madden 12, thanks Jao.
