I reinstalled Win7/64, reinstalled iTunes and am having multiple problems with iTunes. For the last couple of days, iTunes would recognize my iPhone, but when I click Sync, none of the updated apps on the PC sync to the iPhone. Tonight, I attached my iPhone again and this time it started throwing errors saying that it could not connect to the iStore. Then iTunes crashed. To answer the obvious questions... Yes, the computer was deauthorized before OS install and then authorized after OS install. Yes, iTunes was attached to the original library. Is anyone else having problems with iTunes right now? Thanks, Dan.
