Importing - not getting TRK numbers

[hobbit]

I posted this question on the wrong thread, so here's a new one.

My problem is...

Importing files with Disc ID and Track number in the filename (SC8101-01-pearl jam - black.zip) works just fine. However, if the filename only has artist and title ( "pearl jam - black.zip") Hoster will not populate the 'TRK' field in the import screen, though it will still list up to 99 files. However, I get errors when attempting to import since it can't find a 'track' number. Hoster used to just fill that field on it's own, now it no longer does, it just remains blank. The only way I was able to make it work was to manually change the filename so Hoster could read a track number from it ("1_pearl jam - black.zip). However, that will be brutally tedious for a large amount of files.
