Draftsight Stopped Working Since We Upgraded To Windows 10

On 22nd December 2020 we renewed our 6 licences for Draftsight.

The week prior to that we upgraded 5 of our systems to Windows 10 from Windows 7

ALL 5 of these systems are now refusing to load Draftsight stating:

Activation transaction failed: Activation count exceeded. Deactivate a license from another computer and retry

I am unable to deactivate the licences so I can reactivate in Windows 10.

I have uninstalled, rebooted, and reinstalled but still have the same problem.

This is causing us major issues as we are unable to draw!!
