I have mac pro with el capitan,
I had pycharm 4 pro installed from my company and installed pycharm edu 2 afterwards, and they both worked fine even when both opened, until some moment when I opened for some 15-th time the edu edition - at this moment OS hanged completely, and after hard reset I started edu edition of pycharm and it appears the educational part stopped working. I see the project, i can run my python scripts in the IDE, but task descriptions don't open when I click on lessons. I already removed both pycharms from computer (also erased files in users Library folder that are related to pycharm) and reinstalled edu edition. But it still doesn't work as it is expected to. Check out the screenshot.
