Can't seem to open my project. I get the message "sorry, an error occurred reading the project file."
It was made in a version prior to 2.1.08 because I'm using GM Studio. I didn't update it much, the last time I exported from the project file was in December 2015 and I first created the project earlier that year.
I haven't opened it for a few months, tried now after doing a fresh install of Spine and it won't open. I've tried various versions as far back as the 1.x era and I can't seem to open the file.
Any advice? Could it have somehow corrupted? None of my other Spine projects are working either so that seems unlikely to me.
