Contacting support@stardock.com is indeed the right course of action.  We should be able to get both of you straightened out.

Actually, I'd recommend against multiple emails, unless you need to add something important, as it resets the ticket's place in line.    We're not too backed up, though, so you should get a response some time tomorrow.  (I'm writing this from home, otherwise I'd pull it up now)

I'm seeing the game registered to your account, so there's no problem there.  Try closing Impulse and running the following file:

http://sd.stardock.com/curthendzell/fix_registrations.reg

Make sure to follow the link in Internet Explorer, as other web browsers will not handle the file type correctly.  Once you follow the link, save the file and double click it to apply it.  Then relaunch Impulse.  You will need to re-login with your username/e-mail (either will work) and password.

For you, try removing Impulse completely with the following removal tool:

Reboot your computer, then install Impulse from the latest installer here:
