If I convert 10 files, 8 show up on the karaoke machine 2 do not. Why? Many of the files are not recognized by the converter. Why? And how to make them be recognized by the converter?
There might be a possibility that the software is limited only to 8 conversions at the time or you have an old version of the software that doesn't support more than 8 conversions. In this case, access the application's page at Software Informer and download the latest version. You can either replace the currently installed version or remove the installed one and then install the new version.
