polo9, I hope I understood your question correctly.
First: How to register. In Impulse, all you have to do in type in the email you ordered windowblinds with, and your password, and you're there.
If you have windowblinds trialware on your computer, uninstall it using Impulse. If you wish, open the Windowblinds theme file through explorer and save the skins you've already downloaded (save it to another location) before uninstalling).
Reboot.
Open Impulse and download the windowblinds you purchased....
Things should work after doing this. Good luck.
