In the page link posted above, the link is in the Flash file itself. Since it's a template there should be a section that lets you edit parts of it, just like the menu should let you edit the text in the tabs.
In the Actionscript, if you have the .fla or .as files, look for getURL, something like
or in AS3, URLRequest
var url:URLRequest = new URLRequest("http://www.adobe.com"); navigateToURL(url, "_blank");
Your template should let you edit the URL.
Best of luck to ya,
Every template is different so there's no way to tell exactly how to edit yours. Is this template an .fla, an .xml config file, or what? How do you do any editing, to change navigation or add content?
