I’d like to run the «Set Kerning Group» Script but it doesn’t function. I’m currently using Glyphs Version 2.6.6 and I followed all steps described in the YouTube tutorial (mekkablue scripts 01: Install and Update - YouTube) for installing the mekkablue scripts; modules are installed and I did run App > Update git Repositories in Scripts Folder. Other scripts such as Guides > Remove Local Guides in Selected Glyphs do work.
My Python version is also up to date (2.7).
Can someone help met out?
