Ugrade Problem

I am running Logic 9.0.2 and MainStage 2.0.1 on a MacBook Pro 2.16 GHz Intel Core duo running OS 10.6.5. I have downloaded the updaters for Logic 9.1.1 and MainStage 2.1.1, but when I try to run the updaters I get a message saying "Your computer does not need this update." Can anyone explain why this would be so? Will the latest versions of Logic and MainStage not run on my MacBook Pro hardware?
