For no reason that I can see, MM (version 4.1.30.1914) has stopped working on my Windows 10 machine.
When I try to open it I get

Strangely, MM.DB isn't in the Programs folder, it's in Appdata/roaming/mediamonkey
Things I've tried:
Putting a copy of it where it thinks it should be.
Replaced it with a known good back up of the data base.
I've also uninstalled MM, cleaned the registry and deleted any folder I could find, and reinstalled it
Rolled the PC back a week or so to before the erro - it still doesn't work.
Anybody any ideas? Thanks in advance
