I have the latest version of itunes 7.3 or whatever and i'm at itunes store where it shows the itunes plus version. However, it just shows up as 99 cents, with a plus sign... If I click on the plus sign it just takes me to a website inside the itune browser explaining the benefits of itunes plus. I don't know where to find in preferences or where ever to download the higher quality music. Even if I go to the itunes plus section of the itune store, it still shows up as 99cents with a plus sign. I have even reinstalled itunes but got the same problem.
