My shiny new Macbook Air arrived this evening and after setting up wifi and a few email accounts I tried to log into the app store as it said there were 3 updates for me. It recognizes my apple id but when I enter my password I get ConnectionManager::invoke::Failed to find service connection url. itunes is running fine as far as I can see and I am able to sign in to that without any trouble. Anyone else have this problem? thanks.
