But how did you buy it? I think the problem is mostly people who didn't buy from the Mac App Store that are having problems; people who purchased via DVD or downloaded a trial and purchased a license later.
There also seemed to be an issue with people who didn't have the language set to English (but I think these were people who did purchase from Mac App Store) but this got resolved by people temporarily setting their language to English.

I bought it on a DVD, there was no MAS in '10
