Missing Files

[WaltR]

I haven't used Microstudio for a while and today I decided to use it for a project I am working on. I encountered the following problem that I cannot figure out. All my folders are listed by Brand, i.e. Chartbuster, Music Maestro, Sound Choice, etc. I first selected my Music Maestro folder to add, ticked for subs. I did the scan and when it finished it showed 6426 files with no errors. When I click on one of the songs to add to the playlist, I get a pop up message stating "the file is missing". I had the same result on my Chartbuster folder but other folders worked without any problems. These are the same folders I use in Hoster and they work fine in Hoster. Any idea why Microstudio won't play them. They are all mp3+g files.
