Can Not See KMA Files to Burn On CD

[Fredtatro]

Hi All,
Just dowloaded the demo version of Microstudio 3.0 so I could run a test on burning KMA files to a cd. I copied 4 KMA files to my hard drive. I add them to the play list and click on "Add song to write list". I select write disc and I have Karaoke cd selected. I then select Add Songs and direct it to the folder where the KMA Files are. Nothing shows up. I noticed that only bin, cdg & wav files are shown in the "Files Of Type" box. So I'm guessing those are the only files it will recognize. Am I doing something wrong? I read the forum and tried some of the suggestions but still nothing shows for KMA. Does this feature work in the demo? Do I need to uninstall the earlier version of Microstudio? Thanks in advance for your help.
