Just Upgraded to 0.9.91, right click on reflector icon, select OPEN and nothing happens just opens a blank window on task bar (windows 11)

Seems like a corrupted positions file. Delete everything on

C:\Users\<user name>\AppData\Local\CobianSoft\Cobian Reflector

and restart the interface

Just Upgraded to 0.9.91, right click on reflector icon, select OPEN and in my case the interface just closes and disappears from the task bar.
Reverted back to 0.9.90 and everything works again.
Tried upgrading again to 0.9.91 and the problem is back so reverted again so I can keep my backups running.

OK, I see. This is caused by the new Security settings introduced in the last version.

1. Did you have a security password in the last version?
2. Do you have a security password now?

Could you please send me your ini file from the Settings subdirectory AND your UISettings.ini file from

C:\Users\<user name>\AppData\Local\CobianSoft\Cobian Reflector

I think I got it. The error was showing if the engine was not started. Fixed.
