I see a potential problem now with duplicated Disc Id or Book ids.
If your trying to put them on your C Drive you should have just copied the KMA files directly from the USB drive to the folder with your karaoke files on the C drive. It sounds like you imported them from your USB that is why it keeps looking there for them.
Now if that\\\'s the case you cant then just copy them again as you might get duplicated files that wont re import.

So really you need to remove all that you have done so far and start again.

Open the Build database dialog and look down the list of folders in the bottom left list.
Highlight all the folders that match those on your USb drive (with USB connected) that you previously imported from the USB drive and choose Remove folder.
This should remove all those from the database.
If you also see those same folder that you copied directly to the Hoster Karaoke folder, might be best to remove those as well.

Now directly copy the files from the USB drive back to the C drive to wherever you want store them.
Now reopen the rebuild build database dialog and use the Add folders or Add Folder/Subfolders button brows to the newly copied files, if you chose Add folders button make sure you are right in the folder and can see all the kma files then press select.
If you choose Sub folders button it will load all folders below the selected one in the tree.
You should see it load each folder and get a message found X amount of files, if it says 0 files added then either you werent right in the folder or something else is wrong.

See how you get on with that.

It should not be necessary to rebuild the database after this.
