Season upgrade invalid key error

[Certifiable]

I've seen others like this, but no solution written.

Bought Episode one, bought the upgrade, didn't work with an "invalid key" error.

Emailed support, no word as of yet (no emails for hours now). Is there anyone who knows why even with a paid upgrade why the season doesn't work?
(Well, more accurately, just Episode 2 - going in order.)

I just checked the support system and I see that Nick already responded to your email at around 10:00 this morning, our time. (Your initial email came in at 5:45 - we do try to respond quickly, but usually can't get started until the beginning of the work day. ;))

Please review the info here (http://www.telltalegames.com/samandmax/seasonactivation) for details on how Season 1 customers can access preactivated versions of the games. Downloading the demo and entering the order number and password does not work for Season 1 customers.

If you have any other questions, feel free to ask. :)
