no valid or active service account is available to play

Ok, when I log in I get 'no valid or active service account is available to play' any ideas how to get the game working?

I got the PS3 Beta client then when the new client came out I deleted the beta one and now I have been using the new one. All was good last week, but today I logged and I get that message. :confused:

Have you registered your 12 Digit PS3 preorder / early access code via PSN?

Yeah, last e-mail I got was on the 14th. Am I meant to get a new code? I have pre-ordered it off amazon as well, I have registered the code I got from them a long time a go. Still haven't got anything else.
