Well, I'd send an email to support@stardock.com...opening a ticket can't do any harm. I'm guessing (hoping) you're using Impulse so, you have to check what your registration looks like in Impulse.

Click on the question mark (upper right hand corner) and see if things check out there...your registration, serial numbers, etc.

Then click the left upper corner and look at your registrations there "Register a product". See if everything's Kosher...you might have to reregister something.

You can pm me if you run into trouble, Jess.

Jess, I get the same thing and I have over a year left.

No big deal, I'm sure it will be fixed soon enough. 

if you go to the 'updates' tab and try to download from there, does it work? when i attempted to update from the 'my software' tab, i got that same registration message. i then clicked on 'register product'. without changing anything there, i then went to the 'updates' tab. deskscapes then updated for me.

I was on the update page and continually got the error message.

I then noticed an install all updates button under the help icon and when I clicked on it , it updated.

Tried Carguys trick and that worked here

I had the same issue yesterday but the "install all updates" still works.
