Online file saved offline and now doesn't exist

I spent the last two hours working on some sheet music that I had previously been accessing from another desktop. I had saved the score online, so I was able to work on it from my laptop, but my laptop couldn't save the score online. I would hit ctrl+s and it would say that it was saved, but not saved online. After I exited the app and then came back to it, all my progress had been lost. I would assume it is because I technically did not make a new score, and for some reason saving a score offline that with an origin on another computer doesn't do anything. I tried checking my files with no luck. Are there any ways to get this file back?
