HELP: projects no longer open

TODAY I UPDATED AUDACITY, AND WHEN I GO TO AN OLD ‘‘PROJECT.aup’’ as always I get ‘WHAT DO YOU WANT TO OPEN IT WITH?’ I OBVIOUSLY CLICK ON AUDACITY BUT IT DOESN’T OPEN IT!! HELP!! I LOST ALL MY PROJECTS!!??

Try launching Audacity, then “File menu > Open” and select a project.

Your caps lock key (or your shift key) is broken.
