database problems

[rpmzzz]

I'm saying that I have 464 files in my songs folder of the hoster folder on drive c of which 444 are THM2005 -01 to THM 2005 -444. These are in my songs folder. When I get in the program and try and search for them they are there until a rebuild. I imported them 99 at time but used the same id THM2005, and they all show up and work until I rebuild database then all but 99 of the 444 don't show up.... but are still in the songs folder. I tried deleting the songs and songs backup in the database folder and restarting to rebuild and the paths are correctly showing the right folder on c drive. This will be the third time I have had to reimport. Thanks and happy 4th
