Here's a screenshot from the demo site for this theme showing the missing menu:
Are you reading this support forum? There are a number of issues that have been open for the past two months.
The menu is working properly on your other theme SmartAdapt, but I don't have a big enough brain to compare the old code with the new object oriented code.
BTW, I've been looking at themes for the past six months and finally found this one to be exactly what I was looking for. I'll buy the pro version as soon as I can afford it.
