One thing that I saw was that when you clicked on a link, the frame that the content loaded in covered up the rest of the navigation links. And in my opinion there was too much content to read and not enough visuals to entice me. I do like the logo though.
1) You need a homepage link in the navigation bar.
2) The logo is great, but the IX should have a little more white in it. I know it's part of the shield, but the letters fade into the shield too much. Your title should "pop".
3) I don't like the font for the logline at the top, it's hard to read.
4) The fonts in the navigation are cool. Would be nice if they had a rollover effect.
