80. When I try to apply audio harmonies to my song, I get the message "Error or Cancelled out of routine, error code=1".

This error should not occur with PowerTracks Pro Audio Version 12 and higher.

This may occur with an earlier version of PowerTracks if one of the folders in the "Audio Temp Directory" path has a period in its name. Go to Options | Preferences | Audio, and select a different Audio Temp Directory, or use the default directory chosen by PowerTracks. To have PowerTracks select the default directory, you can return the program to the factory settings. To do this, close the program and delete the file ptw.ini from your PT folder. You may wish to make a backup of the existing ptw.ini file first.
