Why am I seeing multiple errors when attempting to use the engine?

I have several problems with the engine. Blueprints & Programming do not affect Actors, Spawns, etc., therefore I cannot build a game. I follow all of your tutorials and its does not work. Should I reinstall the engine and to do so how?

Check your gamemode defaults setup

Can you give some more details? When did these problems start? Do they happen in new projects as well? What version of the engine are you running?
