Using v2004 shouldn't be a problem for this kind of application. MediaLab uses the Internet Explorer browser engine so try opening it in IE rather than FireFox. If MediaLab can't find the html file, the quickest solution is to check where MediaLab thinks the file is supposed to be. You can do this by right clicking on the HTML part of your item. Select properties and then look at the address field. You may have to right-click on it and drag the mouse over the address text to see all of it if it's long. Then verify that the path given matches the actual location of the file.
