If you still see demo-content.kaliumtheme domain on your Product Registration page (screenshot) please just press x button, then you activate your theme again, then you can update the theme and then the premium plugins in the Appearance > Install Plugins area.
I've been installing trying to install the theme and I keep getting an "Update Failed: This domain is not permitted to download the update!" error.
This is the only domain I'm using this theme on so it shouldn't be a problem.
For some reason it shows as demo-content.kaliumtheme as the licensed domain.
