Re Missing KMA Files

[SVENDSEN]

Hi to all,
Since i have upgraded to hoster 4.2, i am finding that when i select a song track number and click add the track an error message card comes up telling me that the KMA file cannot be found, i have found 5 files so far since yesterday.
Also after importing a new disc, and then create the songbook it is saying the total of tracks, in this total seems that i am missing approx 400 tracks, this has only happened since upgrading, is there a quick and easy way to find these tracks that seem to be missing in this new hoster 4.2 program ?
Thanyou
Regards
