Metadata.png

After performing an in-place upgrade of Mezzmo 3.0, all of my metadata (thousands of files) are now missing. Artist, Genre, etc. are now showing numeric values (see uploaded image) and the Title is using the File System name. If I take a new file (no previous metadata), perform the Metadata Search, then click "OK", it does not save the new data. The UI is up, but the server service itself keeps crashing (dump file incoming via e-mail).

Running this 'As Administrator' does not help.

Please tell me the data is still stored somewhere.

OS: Windows 8 Professional (x64)
