The account activation limit is based on IP / Network card ID. You can only activate (upgrade) three accounts from one IP adress / PC within couple of days. The another try is blocked with just Error 202 (?). It can be country/region specific feature, not sure. I had that too in EU though.

There is no official info, since it is anti-fraud feature i guess. The official blue response to deal with Error 202 is to clear browser cache, which is something that can't solve it of course.

I had to use another PC and connection with different IP to finish my upgrades to WotLK.
