Finally found the problem. I didn't buy it from Origin. I bought it as a CD. And being the stupid I am, I forgot to register.
Thanks for trying to help. 🙂
My game worked fine in the past (though I had plenty of problems in the beginning back then too), but when I started it up again after a break, it updated my Origin and now won't let me log on, giving me the same error as above. Origin is a nightmare - does EA truly believe this kind of extreme DRM will counter piracy? On the contrary, people I know who have pirate copies are having no problems and can play the game anytime without problems. Makes me feel like a real sucker for having a legal version, struggling to actually play.
This problem should be fixed now.
Thank you - it is. Got a few strange messages about the server and then it worked.
