If your PayPal email is not the same as your Stardock.net email (the one you use to login to Impulse) then you need to transfer the registration.  Use this Transfer Registration link and put your PayPal email in the Source Account and put your Stardock.net email in the Destination Account.

You may need to restart Impulse for the game to show up in your Games tab.

One more thing you can try -

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.

If that doesn't work you more likely will have to wait until support return to work to get assistance and as this is a long weekend, Stardock support will not be back until Tuesday.

thanks for the help.
It tryd it. No effect

In deed it will be a very long weekend like this -.-

But i used Impulse bevor on the same Computer and never got a Problem.

Since i did not get a Confirmation Email from Stardock i think they just did not got my order.

Its not listet in the Email ;/
But thanks for trying to help me.

I wasn't so lucky with them after months of trying. The irony is that I made the Paypal account in 2005 and never actually used it and a few years later I went to check my bank account and it said I owed over $3000, I only had around $70 in the account at the time. There was around 100 withdrawals, in a roll, of $36 to an online gaming site. I checked it out and it was through my Paypal account. I was careful to use a long password that had nothing to do with me as well. The bank realized it wasn't my fault so they didn't come after me, but neither would they do anything. Paypal just ignored me. Its been a couple years since then now.
