Does it ask for a license?
From what I understand, they removed copy protection from the full product - you either download the demo version with its restrictions or pay and get access to download the full version. No further authorization required.
Though maybe it's just reading my old license, which was installed with the previous full version. But I'd give it a try. Uninstall the demo and download your full version from you user area (or whatever DNR call it).
If that doesn't work, let us know.
