The game is asking for your new(august 27th email likely) retail registration code. It's different then your early access registration code.
You should be able to find it in your inbox or spam folder. If its from SE digital download it will be listed as webhelp.v4 i believe.
If you ordered from amazon you have to go to my orders and find the registration code on their website.
(I haven't seen a fix for the ps3 code yet. Keeping my eyes peeled)
