Hi and sorry for this delay! I had my summer vacation the past couple of weeks.
From from what I can understand from your explanation, I guess you are probably causing some JavaScript error (e.g. by not properly copying/pasting the demo JS code or something) which prevents the script from initializing your menu tree at all. Here is a basic demo I just setup:

Just make sure the demo frame is not wider than 768px so that you can see the menu toggle button.
Hope this helps.
Apart from that, I have planned to include many more demos in the download package in the future so, hopefully, this will happen soon.
Cheers!
