[Plugin: PixoPoint Menu Plugin] Double Bar Issue with Pixopoint Menu

Hello if anyone can help me would be much appreciated. The site I’m creating can be located at http://www.boyslv.com

If Firefox, Safari, Chrome The menu looks perfect fits the width.
But on Internet Explorer 9 it creates a double bar as you can see on the screenshot. I tried removing the background on CSS for “#pixopoint_menu1” that would eliminate the double bars, but the width doesn’t end up looking correctly. If anyone can give me pointers it would be much appreciate. Thank you.
