I've sent emails
You should have received a support ticket number from the first email you sent.
FYI, tickets are responded to First In First Out order so if you send more than one email without first being contacted by a support tech, then your position in the queue drops back.
At times purchases can be delayed for fraud check. This is done to protect the purchaser. Not sure if this is the case with your issue but a possibility.
If you did receive a ticket number please post it here in a comment.
I will attempt to make Stardock support aware of this post.
