I HAVE TWO QUESTIONS. 1) I HAVE A YAMAHA DGX 220 KEYBOARD AND THE STYLE FILE (extension: .sty) IS USED TO TRANSFER DATA BETWEEN THE INSTRUMENT AND A COMPUTER. NWC FILES DON'T WORK IN THE YAMAHA MUSICSOFT DOWNLOADER DATA TRANSFER. HOW CAN I GET NWC FILES TO WORK IN THIS SITUATION? 2) I HAVE A NEWER LAPTOP WHICH I DOWNLOADED nwc 2.5.1 TO. I HAVE AN OLDER DESK TOP AND AN OLDER LAP TOP WHICH ALSO HAVE nwc 2 ON THEM. HOW CAN I DOWNLOAD nwc 2.5.1 TO THESE TWO COMPUTERS? SINCE I'VE SAVED FILES TO THE NEWER VERSION(2.5.1), THE OLDER VERSION(2) WON'T BE ABLE TO OPEN THEM.
