Highend Theme Options Lockis Up

Unfortunately, I get to give you guys the chance to prove your customer service is as good as you say it is.

I downloaded Highend Theme last weekend. Every time I go to the Highend Theme Options page/menus, it allows me to select exactly ONE menu item and then locks up on me. I have to pull out of the entire thing and restart. Then it does it again. If I’m not mistaken, it did not do this the first time or two I used that page/menu.

Yes, I’ve tried deactivating every last plugin. It didn’t help. I’m running the most current WordPress.

What can I do?

Thank you for your help.
