Hello. I launched the app and it was still activated. I have had at least 1 PC restart since the last time I had to reregister. I tried the following to force a repeat of the behavior:
Chose Help/About/Change License Key. Entered a bogus name and key to force the program to unregister. Restarted the app and it was unregistered.
Entered the correct registration key and name. Restarted and the app is registered.
Restarted the PC.
App remains registered.
Not sure if this is helpful since the app was in a forced unregistration versus starting in the unregistered state I have been experiencing. I am happy to further troubleshoot.
