ALL Tracks are Silenced

First appeared some erros: failed to load…
Then the program started to freeze a lot
In the end, I think I clicked in the buttom “anular”= anulate in Portuguese, I’m in Brazil.
Now, All the TRACKS are silenced!!! And I don’t see how to recovery. Even the last saved files just became Silenced.
I took 2 months to complete the song, Lots of tracks and so much creativity for what? Loose everityhing.
This buttom should NOT exist. I didn’t know that It would ERASE the whole Projet in cluding the history.
:cry: :astonished: :astonished:
