Greeting Mr melody86

The Lame software is in a folder inside the Audacity program folder. You should Save or Export your work to My Music or other working folder, not a program folder. An Audacity upgrade should not change the FFMpeg or Lame software, so your work should still be there. Search the machine for one of the music filenames and see if it hits.
