Well 4 days on from buying the game on Origin I still haven't been able to play it.
I have spoken to 3 different advisors who have now escalated the issue on to a "specialist" who is apparently going to email me back. I've been waiting 3 days now.
I won't be downloading or purchasing anything via Origin and will be very reluctant to buy EA products in the future.
Perhaps the uninstall of the previous one didn't remove all references to the registration key in the registry? I'm not sure where I would start looking, but if you happen to know your original registration key, you could do a search in the windows registry on that and see if anything comes up. (I would actually only search the first part before the hyphen)
I don't have any better thoughts at the moment.
