iTunes no longer checks for App updates
I can search and purchase apps on iTunes. I can look at my iTunes account and redeem gift cards and the help-check for updates works because it found the 10.1 update today and I installed it. Everything seems to work fine in the previous version and 10.1 except checking for app updates. It seems like it can't access the iTunes store here.
Two other computers (kids) in my house with iTunes work. I've disabled norton and it stil doesn't work.
Can anyone help me?
