Highend Theme NOT working

Hi,

I downloaded the high end theme to my wordpress, then installed the demo to edit with media composer, but its not working – its super slow, and the menu keeps repeating itself down the page. I’ve been trying to fix it – I’ve increased by host memory and speed, but nothing seems to help. I emailed the support team two days ago, but have yet to hear a response. Please help.

Thank you,
