Missing
- Context Click on the sort column header bar (where it says "Name | Artist | Album" etc) and pick "File: Zip" (assuming it is zipped, otherwise pick "File: Audio")
- on your missing song, look in this column, you'll see the path at which kJams believes the file resides.
- discover where the discrepancy is, compare the path to the actual path to the song as you trace it in the finder
This should be enough for you to know what happened. If you changed a path and you need it changed, make a symbolic link (not an alias) from the old path to the new path. Otherwise, just change it back. If you renamed the volume, you have to rename it back.
If you've tried everything and it still doesn't work, let me know and i'll fix it.
