When I try to edit an audio track associated with a video in Vegas 13.0 using SoundForge Audio Studio 13, it opens okay (I use the "Open Copy in SoundForge XP" option) and I can edit the audio track just fine -- but when I try to save the edited audio file I receive the following error: "An error occurred while saving one or more files. The file could not be opened. Make sure the file exists and you have access to the file/folder." By the way, this is a new Vegas and SoundForge installation. Everything else seems to working fine, but how can I correct this problem?
