Musescore "doesn't support this version of mscz files yet". Help?
Tried to upload a pretty big score (orchestral and about 50 minutes long) and got the message "The score cannot be uploaded, as we don't support this version of mscz files yet. Sorry for the inconvenience". Tried to then upload the score to youtube, and it sent over the audio of the old version of the score with a blank screen throughout the video.
Is there any fix?
