I am using version 6.5.8 (old, I know, but it works great) and have been using this version with no problem since its download, whenever that was a few years ago. Now all of a sudden I can't add a sound file. When I try, it hangs up and crashes the program eventually. I am trying to add mp3 files. I tried ones that I created in audicity and single songs that I have downloaded and used many time before. I haven't changed anything on my computer.. no new software... no new hardware. I can open and play existing shows but cannot modify the sound track. Not sure where to turn - hoping someone can help me out?
