When I first tried to edit an export configuration I was asked which default app to use to open .mte files. I specified mp3tag and now I am unable to edit the configurations. I then found that there is another thread which suggests that you should use Notepad as the default app. However, when I go to change the default app in the Windows settings I only get the options to use mp3tag or find another app in the Windows app store which gives me no other options whatsoever. Can anyone suggest how I can get the association changed?
