If you have a copy of the original cdg, made by Microstudio with all 15 tracks, then you should be able to import the 15th track from the new copy. Since Hoster could not read in the 15th track from the original cdg the display in the import list should show track 15 as not loaded. Load your new cdg into your cd reader with Hoster up and running, and 14 tracks will show imported. The 15th track will indicate that the track has not been read in. Just check (click) track 15 and click on "Import Selected Tracks". Track 15 will read into hoster with the same ID number as the other 14 tracks.
Am I making any sence
