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"
KTF!
