itunes claims I'm not connected to the internet, but I am
I've tried signing in to the iTunes store numerous times, using version 11.0.1.126. Every time, I get an error message telling me to check my internet connection (which is always connected when I make the attempt) or even claiming that I'm not connected to the internet when I most definitely am, and every other internet app on my computer knows it. And yes, I have permissions set in windows firewall.
Is it possible to make iTunes detect an internet connection once it's made up its mind that it's not there? If so, how?
iPod touch, iOS 4.2
