Do you mean the Main page? The Marquee is the text that scrolls across the top of the Show Display on the TV.
Check to see if the disc drive you are trying to import from is the set default drive (Tools/CDDVD Drives) and that it is capable of reading CDGs. Additionally check the disk itself for scratches and cleanliness. These problems can cause the disc to not read.
You can not add songs to the playlist on the main page directly from this utility. You have to import them with an assigned bookID, then close the import window and add the song to the playlist from the top of the main window by adding one of the bookids and clicking add track.
