this may be a long shot ninja turtle, but make sure when you click on the charts addon folder, your next folder inside that is the data folder, etc. Sometimes the way zip files work is you may see another charts addon folder inside the first one, if this is the case the mod will not be installing in JGSME. Usually a sign that the mod is installing will be a JGSME warning that you are about to overwrite this or that file, which is what you want to do....good luck
