If you a 1.0 player and log in on PS3 you can. If you are not 1.0 then you are officially stuck.

EDIT: I see you have a PS3. Just play on it until August 30th or when you get your official registration key and then migrate to PC. As for the service account issue, you haven't linked your SE account to your PSN account? It should be something that should be working properly in a few hours.
