I'm pretty disappointed. I tried several times to claim the OTC key, and the reply email would take a very long time to arrive (1 hour and 21 minutes in the one instance where I bothered to keep track). After finally receiving and I opening each email, I'd get an error message which I assume has something to do with the key having expired due to the amount of time it took.
This morning, I finally got an email response after about 45 minutes, but upon clicking the link, I got a "403 Access Not Authorized" page. Now when I go to the key offer page, I get a notification that the promotion has expired.
The irony is that, in creating my login to post this message, an account activation email arrived to my inbox within seconds.
I guess I missed out. I tried several times and waited hours for emails to arrive and have nothing to show for it. Frustrating.
