I upgraded from XP to Windows 7 and the above error appeared when I tried to save an edited file using Music Lab 10. I thought by upgrading to your Music Lab 10 Premier (which is compatible with Windows 7) would solve the problem.
After trying to to save a transferred file, this same error message appeared.
After installation of Premier, I also did a download of the update from your website.
Also, when I opened the Audio Edit window of Premier and played a clip, audio played fine but the progress bar never moved.
Any feedback would be greatly appreciated.
