Highend Options editing screen freezes

I created a new blog and purchased Highend this week. I was able to get into the Highend Options editing page and click around in it once – I tried to change the map marker and change the favicon. But my settings didn’t save, and now every time I click into the Highend Options editing page, the page simply freezes. None of the other admin panel buttons work in this screen, either. The only way out is to click on the link to the front/main screen of the site.
