LICENSE KEY DOES NOT WORK FOR NEW DESKSCAPES RELEASE

Today, this AM, I ordered the new Deskscapes 2026 version.  When I received the license key, after getting the invoice, I downloaded the software.  After the full download, with no problems, the Stardock box for license key information appeared.  I put in my correct email address and copy/paste the license key that was sent to me by Stardock.  Problem is, I automatically received an ERROR CODE 212, telling me to contact support for assistance.  I haven't even tried the software yet and it is already screwed up. Any assistance would be appreciated, thanks.
