Load Error, Cannot read file
I was working on an arrangement in musescore with a double staff accordian part. I decided I didn't need the bass clef staff so I went to Edit > Intruments and deleted the accordian bass clef. Musescore then promptly crashed and I have been unable to open the file since, instead I get a load error: "Cannot read file". Does anyone know how I could fix this and get my arrangement back?
