Help with Spaces on Nav Buttons

I tried to make a navigation button bar, with, all the the buttons. Each button is the same width. But when I put them up it shows like this:

There is a small space in the navigation menu. My forum is here, if you want to see what I mean.

I even tried forcing the navigation bar on one line, but it still looks like that. Does anyone have any ideas.

EDIT: I fixed the problem, this can be locked now.
