Problem with menu alignment

[Chris_Evans]

Hi there,
I've got a problem with menu alignment. If you take a look at:

http://www.konectforums.com

...the menu appears differently on that than it does on:

The css stylesheets are located here:

http://www.konectforums.com/templates/subSilver/stylesheet.css

and here:

http://www.konectforums.com/othersite/style/stylesheet.css

I can't figure it so hoping somebody may be able to.

Thanks in advance,

Chris

PS: I haven't as of yet checked this page with any other browsers other than IE and have yet to perfect the code in terms of tidyness. :)
