[SOLVED!] Files lost because of a "Do not save" accident.
Okay so I was recently working on a piece of music for about 4 hours. Then I go to look something up on the internet if there is any patches on Articulations, such as cresendos and stuff. All that to the side, I was just browsing the internet and I click on this link a musescore user had in their forum, and it brought me to another piece of music that someone already had created. Then I go to exit out of that music, then boom something TERRIBLE happens. I quickly (without consent) press "Do no save", thinking it was the other music I didn't compose. So I've tried looking things up for help and support and nothing has clicked in me yet. I'm so mad right now I can delete MuseScore off my laptop. So now I have the other music saved, which isn't mine and now my original is just gone. It's like my hard work just dissapeared and I feel like I wasted 4 hours sitting on my couch. I could've spent those four hours with my mom or something.. Can someone please help me? Maybe there is a solution that can resolve this accident? Please respond ASAP thank you.
