I'm having this same problem. I never received an activation email, but can't get another activation email sent to me because I'm 'already activated'. Hopefully they'll get it resolved sometime soon.
I'm having this issue too, it seems like the only page i can actually get into is the "My Software" page. But even then clicking on anything in there brings me back to the Resend Activation page
Everyone seems to be having this problem. You can download directly from FB but then I got an error with my product key.
I've filed an error report.
I hope everyone here has also filed error reports. This problem has been going on for a while now.
