Hi guys!
Unfortunatelly I jus had the same problem. I was working on a file and in the next day I couldn’t open it. Glyphs is still working with other (new) files, but as soon as I try to open the file that I need it doesn’t open.
Would like to avoid to annoy you with this but I guess you’re the only ones who could help me.
Should I e-mail you the file?
