MTU.Community - cant find mark song

Copied from the Manuel:
It only works for songs that are in your Songs Database. It will not bring up the Mark Song dialog window for any songs added using the Koke, Audio, or Video buttons. It also doesn\\\'t work with songs added using the Singers Disc button.Your note, the song name and file location will be written into the C:\\\\ProgramData\\\\mtu.com\\\\Hoster\\\\MarkSong.txt file. You can get to this file by clicking on the Mark Song button when no song is playing, or by clicking on Tools Menu > Hoster Data Folder. You can open the \\\"MarkSong.txt\\\" file by double-clicking on it in there.

Once you have addressed the songs that you have marked, you can delete the MarkSong.txt file from the folder, erase the entire contents of the file and save it, or right-click on the Mark Songs button and choose Clear Mark Song file to start again from scratch
