Can you be more specific? What do you mean by broken?
I have heard of some people having problems but have not experienced any myself.
Is there a yellow triangle in the lower left of the window when you view the course in a browser? If so, there is something wrong with the course that Lectora is not catching. To begin with, make sure you did not use any special characters in the name of the course or any of the page names. Dash and underscore are okay.
