So I specified my email address to log in, and it used the "trial" mode license.



That has expired since the 10th, and now it won't let me unregister -



Exception

   Unknown Adapter



Source : MicroFour License Base



Stack Trace:

at Activate.ActivateMain.RequestDeactivation()



Suggestions are twofold:

1. Don't let it activate if the license is expired

2. If the license has expired at any point in the past, let it succeed in unregistration. Typical pattern would be to download trial, try it for a while (And yes, possibly buy before trial period over, but should have option to buy after trial period ends)
