Mezzmo lost the main database by moving itself elsewhere

This evening I found all my playlists, files, everything were gone fwhen I browsed Mezzmo from any device, and Mezzmo was serving up a number of strange folders I didn't recognize, all empty. It appears that instead of using the Mezzmo database I have in 'E:\mezzmo_database', it had suddenly decided to revert itself to looking on the C: drive. I believe there was an update a few days ago, perhaps it happened then.

I noticed just in time that when I was asking Mezzmo to change the database back to the correct place, it was proposing to copy the 'empty' database on top of the 'real' one. I'm currently waiting half an hour for the (large) database folder to be backed up then I'm hoping I'm back in business.

Has anyone else experienced this ?

We have not experienced this. What version of Mezzmo are you running? Go to the Help -> About dialog to see this.
