Crashes and freezes

It baffles my mind that the app keeps not working (El Capitan), even after the latest update. When I try to access the preferences the app freezes. It’s really not professional from a paid app (that I paid for both iOS and Mac OS X!) to not solve this issue after weeks, and to release new versions which crash anyway. It’s upsetting!!
