SGP stops loading mid-startup

Have a new issue, SGP (ver .21 and 17 and 16) fails to load and stops working. It worked the last time I used it.
Win 10 64 bit. It freezes at the Initializing Modules (Retail License at bottom) screen and closes down.
I normally run it as Administrator and never have had an issue. Loading versions 16 and 17 give same issue.
Running Windows Compatibility troubleshooter gives same problem.
Any thoughts?

Take a look at this thread:

Now it’s working. Just as the referenced thread, I moved all the profiles out of the following directory:
“C:\Users\YourUserName\AppData\Local\SequenceGenerator\Sequence Generator Pro”

and then deleted the entire directory:

"C:\Users\YourUserName\AppData\Local\SequenceGenerator

then reinstalled version 21 and reloaded the profiles back. All works fine now.
Strange but happy.
