Oh the e-drama. Christ dude, its a BETA! Stop throwing your toys out of the pram.
If you haven't received your activation confirmation after you've submitted your beta key then I'd re-enter it if I were you guys.
Hardly, if they can't get it right so close to the release I can't see myself bothering with something I didn't really follow from the start and only wanted to try out. I may just wait when a few months down the line when they release a free trial.
