iPad no longer authorized error

Just trying to sync my iPads on my Mac Mini... Everything was fine until yesterday. But today, NONE of my iPad will sync (2 iPad Mini, iPad 3), every iPad will pop a message saying:" Ipad cannot sync because the computer is no longer authorized to transfer the purchases.."

I do not remember I de-authorized this computer and reauthorized does not help.

I am very mad now because I cannot get the god damn iPad to sync. This is frustrating beyond the imagination.

UPDATE: All iPads running iOS 7.0.2
