Purchased full license cannot open Glyphs

I have just purchased a full license for glyphs and cannot open the application which will not open. I am told Glyphs quit unexpectedly.

Please help.

Redownload the app from glyphsapp.com/buy and try again.

And read this, perhaps: https://www.glyphsapp.com/tutorials/how-to-install-your-glyphs-license

Hi was hit with a bug that was solved in version 2.3beta.
