heres my code for the form too:
<p>Your Name (required)
[text* your-name] </p>
<p>Your Email (required)
[email* your-email] </p>
<p>[submit “Send”]</p>
It looks like Ajax is not working. When I submit the form on your page it -should- be an ajax connection back to your server, it gets the download link from the server, and then it puts that download link into an existing div on the page. Instead, it is submitting the form like a normal non-ajax POST, which clears the page & loads it again with that message at the end. That’s why it doesn’t work.
Ajax probably doesn’t work right because the EventManager javascript stuff you have. That would be my first guess. Another thing I noticed is that when you open firebug (or chrome devtools) and then load your page, it logs javascript errors for nav.js and search.js saying something about window.addtype not valid. So, it looks like you’ve got some conflict issues with your javascript or with plugins or theme or something that is using javascript. You’re on your own figuring that out… if you didn’t specifically add the eventmanager stuff yourself, then disable as many plugins as you can & try again.
