Recently got license

I had been using the tutorial and recently bought my license. But glyphs won’t open at all saying that my trial period has ended
Edit: I have purchased glyphs mini and am using the glyphs mini app

The license is a file you have to download and run. It’s been a while since I did mine, but it should give you a message after you run it to tell you the license has been applied.

I’ve downloaded and tried to run my license and it hasn’t worked

Have you tried all steps in this tutorial?
