I have downloaded the sound forge 15 program 6 or 7 times over a two day period. Every time I get static over my music playback. I've used sound forge 10 for many years, had no problems. Please help I have a brand new DELL INSPIRON AIO 27 DESKTOP. if i can't get this new version to work, can i use my old version of sound forge 10 on both of my computers?
