Yes, it does appear apostrophes are a problem - I'll get this fixed in the next version.
About not all playlists being exported - this is deliberate. The purpose of this script is to backup your AUTO
playlists - this is in the description in the first post. The parents are only exported to keep the structure in tact. To export all the manual playlists would mean exporting all the playlist tracks which would also mean exporting all the tracks. Basically that means exporting the entire database, for which you should use my "Backup" script!
