A personal piece of advice:
Get rid of whatever that is that asked if I wanted to install Java Virtual Machine (on IE6. With Firefox 0.8 I just adblocked it). Many will leave your site just for things like that, not giving your product a chance. Keep the site simple.
Plus, that thing is apparently a centerpiece, so it also messes up your page on both browsers, (too wide) until you decline and close the window(s) and go back. Then it's okay.
