Ok her is the scoop

*lame line #1*
First thing i looked at were tools on the background... Do you want that to happen? I think background should be just a light shade of grey with right menu/table featuring pictures/info about your program. For example, cover of the cd, maybe a sentence or two about the product and reviews of the product, punch lines. Such as BEST PRODUCT I HAVE EVER USED. HELPED ME FIX MY CAR IN INSTANT. Or something creative like that to spice up the page *im sure youll have 0 probs with this one*. (lame line #2)
Second thing i noticed are the buttons, ok lookig good, but WHAT'S THIS, they don't seem to work, then i realized they do work but the grey layer background was so confusing, i could hardly tell when the layers pop up. Maybe switch the color of the layers to differ from background, so it looks like something is popping up, and i don't have to eyeball the page to figure out that the layered menu has popped up. (i use word popping too much)
Then i thought that the top navigation menu and left menu are too close together. It is to your preference of course, BUT it was a bit confusing. First layer menu coming up so close to the left hand side box looked strange a bit. It gave me that *what am i looking at* feeling and i had to focus to figure out whats going on. That might not be the effect you wish to perceive for your visitors. (you confused yet? I am)
I am VERY intrigued by the project, i read the whole preview of the cd and it is mind boggling that you could possibly fit so much info on a cd WOW. I admire you greatly for that knowledge. (can we be friends when you get real rich??!!!)
Upon another look my suggestions would be, and these are just general suggestions that you might want think on

(yeah right, better change the site or Ill email you 500 times with blank emails... jk)
One: Change the background so it blends in more.
Two: Change the color of top Navigation bar so people KNOW it is a navigation bar, maybe change the text color on it or make it stand out more, as it is now nav bar blends in quite a bit, and it is harder than it should be to recognize it's importance.
Three: I know you will do this, but im recommending it anyhow

Add some pictures, on maybe right hand side table/layer etc. Some quick info about the product. Your contact info. (hehe made me look good to point out obvious facts of what your going to do next)
AND MOST IMPORTANT, KEEP UP THE AWESOME WORK, with your knowledge of scripting your website will be eye candy and something people will flock to, for all their car problems. BAM, ultimate goal in web design achieved.
As Amy said, *Good job ole chap!* VERY nice work WebMan, i can honestly say im impressed. (can i have a dollar) How about e-mailing me the script for the menu now
