Siri not compatible with Yahoo Sportacular Pro?

I am very excited about the updates with Siri in iOS 6. Particularly in relation to looking up sports scores. However, I've noticed that when I try to follow the link, I am told that I have to have Yahoo Sportacular installed. So I did. The Pro version. I hate ads and would rather pay a couple of bucks to not have them. However, even after installing the pro version, I still get the same error. Is there a setting I'm missing somewhere? Or does this really not work with the paid version?
