Kazaa has been on the steady death-rattle for some time now. It sucks. The program is fine and all but its advertising has been getting worse and worse. In addition, Kazaa has pending lawsuits that will probably shut the whole thing down soon. Jump off the sinking ship man. Go to Morpheus if you like the interface of Kazaa its basically the same thing with less to complain about.
I don't know why any person would download Kazaa when they can get Morpheus!
