I recently updated to itunes 7.7 after learning about the app store for iphone. I was running itunes store fine this morning on the earlier version of itunes. The moment 7.7 was finished I got an error saying " Itunes could not connect to the itunes store, an unknown error occurred please check your network connection" My connection is obviously not the issue because I can connect to the internet fine. Any idea what to do? I already uninstalled and reinstalled itunes and that didnt help.
