When MuseScore switched to a paid model, all of my scores were lost in the system. It shows that I have no scores at all. I contacted MuseScore support, and they verified that there is only one account tied to my email address. They recommended that I post my problem here so support can take a look at what might have happened with this. I would love to continue to use MuseScore, but if the scores are going to be lost, I'll find something else.
