i just reinstalled yesterday and had this same problem..searched the internet for about an hour and finally got it to work.
if when you try to get online it DOESN'T make you do any updates, then all you have to do is go to login and make any name and pw up and it will work, don't go to create an account.
if when you try to get online and it DOES make you do updates, then you have to disable your computer's firewall AND any virus protection programs in order for the download to work. (You can re-enable them immediately after the updates are downloaded...the online game works with the firewall/anti-virus on).
I know my post is kinda late compared to when you originally posted...but maybe if you never got it resolved and you check back in here at some point this may help.
