Library not showing any karoke tracks

Iv'e been using QMidi a number of years now on my MAC
Iv'e recently gone through all my karaoke music using QMidi (15,000 karaoke tracks)
I right clicked and selected missing files - two files were displayed in the list as problem files - I removed these files by selecting them and using Alt Backspace to remove them from my machine.
I now have a blank QMidi Library screen? I can't seem to be able to view my songs?
When I exit the APP it always displays a blank Library? How do I get the database working (displaying) again? Ive had a look in the MUSIC/QMIDI folder and the database is there 20.9 MB
Thanks

No Time Machine backup?

Send me the library file.

Its OK - I created a new database (or at least I think I did).
All the data that I edited in the Track(s) Info eg (Composer) was still all there?
Is it stored in CDG part of the file?
All I had lost was the Number of Plays, Last Played info and the KEY I had altered the some of the songs to.
If I want to back up the database is it just the big file QMidi_Library.sql or all 3 files in the folder?
