Is this because I preordered it and its not out yet
Correct, your order will be completed and you will recieve your serial/download access on Monday/Tuesday.
Going to save myself making a seperate topic and save your support guys an email, if you can answer this question:
I purchased two copies of the collector's edition, one for myself and one for a friend who I constantly game with, especially in team based games (We tore up poor souls in both HOSK and DotA, so he's interested in seeing how good people will get in this game with time) .
I used the same email for both and sent them both to my address. If I register on Impulse with that email, will it the auto-populate screw anything up? I'm worried it may lock up the serial so I can not hand it to him to use after I hand him the download.
