I’ve problem with opening any document in glyphsapp.
I was working on my project, and I tried to open some .otf files to look at during designing my own letters.
Then I get message “The document “blablabla.otf” could not be opened”.
I thought that restarting Glyphsapp could help. I did it and this time I wasn’t able to open any file in glyphs.
I reinstalled Glyphs, even upgraded from trial version and still nothing.
I’m able to create new font, edit it, save it. But then I can not open it.
I’m on Glyphs 2.0.0 (726) and having the issue. License has already been installed; I even tried dragging it back into the app. Note that it’s not a specific file, but all Glyphs files, which refuse to open.
FWIW: OS X 10.10.3 G2.0.1 . I did some tests after reading about the problem. My fonts are always built as PostScript, and I do not have any problems opening either the original files or the exported fonts from several different projects currently being worked on.
