Why is 'statement three' outputting to the console but 'statement four' is not?

Description Of Gist.txt

This a gist about an audio plugin that plays a single audio player. 


On line 83 of MainComponent.cpp I am getting the error: C2280	'LoadSaveXmlFile::LoadSaveXmlFile(void)': attempting to reference a deleted function


How do I undo a deleted function error and make Statement four output to the console?
