Center MENU on Homepage

Current Theme: Arras 1.5.0.1

Here is the site:

Now here is what I’d like the Menu to look like:

I tried all of the <center> stuff.. Did not budge.. I’ve had it centered before, but I had a flaw somewhere in my html code for another feature so I reinstalled the original and cant remember how I centered it.

I believe I enter 80% or something somewhere or used pixel alignment, I have no idea to be honest.. I’m very html illiterate.. 99% of my html success is trial and error, but I can’t seem to figure this one out…

Thanks fellas..
