Mixvibes Home 7.2 crashes on startup

After scanning my USB external harddrive for MP3's, the mediabase looks OK. I have 20.000 MP3's. I noticed some tag information was not included in the mediabase.
When I shut down Mixvibes Home and start it later, it will automatically reload the last used Mediabase (untitled in this case), and it crashes. Renaming untitled.vbs will make Mixvibes start again, and the situation repeats itself.
Saving the Mediabase before closing and opening by double clicking on the saved Mediabase will make Mixvibes crash too. Effectively, I'm unable to load a named mediabase without crashing, rendering the software virtually useless!
