I have a 40 minute mp3 file that was created with ACL that was saved with all tracts in one file. I copies this file to a separate folder and renamed it and began cleaning up the copy file. Some where I made a mistake and exited the program without saving the project or mp3 file. Now when I open up either the copy or the original file, I am only able to retrieve the first two tracks. All 12 tracks play when I open the file with any mp3 player. I have removed all of the project files I can fine, rebooted the computer, Dell XPS running Win 10 Pro.

Is there a history file somewhere that retains setting that I can clear? Any suggestions to resolve this would be welcome. I have recorded other music from vinyl since this file was created with out issue. I really don't want to try to pull this albumn from vinyl again.
