I have an active subscription to Object Desktop. It almost daily keeps asking me to re-register products that I've installed with my serial number, even though I did it a day or two before. (I re-register each time by linking to my account, and yes it accepted the registration each time). I have experienced this bug in the past and assumed they would have fixed it by now.
I'm pretty certain this is a side effect of the site recovery which Stardock is undertaking still, and yes, I'm being affected also.
I know it's nothing to do with anything at my end, it's the Object Desktop records at Stardock being 'forgotten' with some DB recoveries.
With a little patience the adverse effects of this should go away ...
