I've started LevelUp from the extensions window. The banner with "loading..." appeared but has done nothing else for the last four hours. I've tried closing and reopening both the extension and Photoshop. Also tried restarting the computer.
Sorry to hear about your troubles. Are you still experiencing this problem today? This type of issue is often linked to a spotty Internet connection.
I'm having the same problem today. My internet connection is fine.
