Can´t open glyphs

i just got the license for Glyphs2, the download ist working, but i can not open the program.
When i drag the license file into the Glyph2 icon, there comes only the information „thank you for register Glyphs2“.
Why is it not possible to open it? Maybe you can help me. :slight_smile: thx

Just open a new document from File > New.
