Cannot read Minimserver music library

[Peter@57m]

Since successfully getting Lumin to load all my library, I added a new CD and after restarting MinimServer, Lumin reindexed and I ended up with only 27 out of 650.
Since then I tried reinstalling Lumin, 1.2.5 and 1.2.2, using 4.0.2 and 3.8.3 firmware on QNAP, shutting down entire network and only bringing up NAS, KDSM and iPad and everything else I can think of.
All to no avail, not managed to get even 1 album loaded to Lumin
Totally frustrated by this.
I suspect its some network issue or some software behaving badly on the network but I'm out of my depth now.
Reason I say this is that MinimServer and Twonky running on the NAS as well as some other sources appear erratically in both Lumin and Kinsky
