After updating both IDEA and Scala Plugin, my most basic Scala code doesnt compile. In fact, it doesnt even seem to recognize scala keywords like actor and self. As far I understand, project structure is set correctly (or maybe not). Can someone put together a list of things to set under project settings please? I tried to invalidate cache, uninstall/reinstall, update plugings and all other obvious things - still nothing. Very frustruated and any help would be insanely appreciated!!
