Old MuseScore won't read New musescore score
I am currently using Musescore 2 on Gentoo linux. Because Gentoo hasn't bothered to update Musescore to the latest, I am forced to use Musescore 2.
I used to run Debian Linux, and at that time I had the latest Musescore. Everything ran smooth then, but now that I try to run a score that was made with the latest Musescore, my version doesn't know what to do with it.
Below, I have attached three files. Two of which are the errors I get when trying to load the score, and one is the score itself. The score attached is not an image, so you should be able to open it with Musescore.
If someone could help me out, that would be great!
