Yes...just so happens I do. 
Merge the two accounts you created:
https://www.stardock.com/support/registrations/
I would suggest merging the new account you created after the purchase ("Source Account" on the left side of the page) with your trusty old account ("Destination Account" on the right side of the page).
Actually, Stardock probably did respond (auto-reply) and that response is probably in the email account associated with your first account, or in a "spam" folder there. Stop writing to Support until you find the "Auto-replies" since you're kicking your request for help to the end of the queue each time you do. Support works 9-5 Eastern Time, M-F. Depending on the number of requests for help, the response from an actual support person might take a couple of days.
If the merging accounts doesn't work, then find where the 'auto-reply' went, because that's where the actual Support person's response will go. Make sure to "white list" email from Stardock so it won't go to that 'spam' folder.
Hope this helps.
