Answer: 
You need to change the window mode of your swf to transparent. Here is a link : <http://kb2.adobe.com/cps/142/tn_14201.html>
I don't think the window mode will happen. That just makes the flash background transparent.

You have a different issue - the menu is below the flash. I looked at the code, and it seems like you are using an iframe with whole new html wrapper. I don't know how you made that website, but the menu div comes AFTER the div that loads the iframe. Swap those and you should be good to go.

If that code is generated by something, try figuring out how to generate the menu first and then that div that loads the flash. 

hope that helps
