Itunes radio, step by step?

[UCLA Bruins Fan]

I can't seem to get Itunes radio to work correctly with VO.  When I  
interact with the table of catigories the mouse seems to jump to row  
20, and the only thing that is expanded is the christian music  
stream.  How do I get this to work properly so that the mouse lands on  
the stream I want to listen to?
Thanks, Olivia
