I have about 4000 songs and only 500 show up

[UPNext]

I am a new Hoster user and things have been going quite well. I've already done a few gigs with it with very good results. I thought that I would break down and read the manual to make sure I was utilizing the software as best I could. I noted all the Windows Tweaks that are mentioned and did them and all seemed fine. I also had noticed that I had incorrectly listed the artists names on several duets so I edited them so that they would show up correctly in the songbooks. I then rebuilt the songbook and it told me that it had 518 entries when it should have about 4,200. I tried rebuilding it again to no avail. I verifed the path to the directory was correct and it is. Then in desperation I uninstalled and then reinstalled Hoster and unfortunately got the same result. I can see all of my songs so I know that they are there. I just don't know why Hoster can only see some of them. Any ideas would be greatly appreciated.

Thanks,
