SOS ASAP

Hello, I cannot get my file to open. It keeps saying score invalid when I try to click on it. I had a great start to the piece, as it is my final from my chorale arranging class but musescore gave ut on me. I can see everything I had in my picture, but online I can't see anything and I had saved it multiple times last night while I was woking on it. What is happening and can you help revive my score?
