Apple Store on iTunes help

A little while ago iTunes wouldn't load the store, when you click on the store it would load halfway up in the menu where the stuff tells you what's being processed or playing. And I also can't drag music files into the music library with the Music library being opened. I tried deleting iTunes, everything thing else that deals with apple in the Add or Remove Program control Panel except for iCloud and Mobile Me Control Panel, because you can't delete Mobile Me. I was wondering if there is something that I am missing that it isn't allowing me to load the Store or add music files.. Any help would be appreciated. Thanks..
