How are you adding files to a Playlist? Are the files in the Library?

Hi there,

I have recently moved my mediamonkey to run off a portable hard drive as per instructions here [url]http://www.mediamonkey.com/wiki/index.php/Portable_Mediamonkey[/url]

Problem is, when I now add files to my playlists they are not appearing which is strange - could this be something to do with .ini file? where should I be looking?

thanks for the help
