harrysdog, there's nothing to download. It will just come up automatically - it's a new website, has nothing to do with the application you downloaded.
The main page looks almost identical to the old one. However, there should be a couple of new tabs on the page: "My Qtrax" and "Charts."
If you scroll down to the bottom of the page and look in the lower left corner, you'll see the version number. It should say "Qtrax Version 0.3"
