Sorry about that

Did you install or upgrade Hoster after adding the song files ?

I know that if you upgrade from an earlier version of Hoster It moves the Hoster folder from C\MTU\Hoster to C:\ProgramData\mtu.com. I thought you already had it installed, I don't think it would still move the Hoster folder after 5.10 had been installed.

Having your actual song files in that folder could be a pain in the future although they will still work OK.

I would personally move them. To avoid the Hoster folder problem. I should just create a new folder in the C\MTU folder Named something like "Music". Then either Move them from inside the C:\ProgramData\mtu.com\Hoster folder to your new folder or delete them and re copy them from your external.
The File tree will be like this:

C:\MTU\Music\karaoke
\Audio
\MP3+G

Before doing that though it may be best to remove the existing file paths from the rebuild list using the "Exclude Folders" button so as to clear the database first.
If your not sure what I mean, open the Rebuild database dialog select the 3 file path in the list by using CTRL+click then press the Excude Folder button. This will remove those files from the database leaving you with an empty database. This should prevent any duplicate ids when you add the new file paths to the import list.
