Ive had a little issue myself with the security key in my CE. I got my CE box on Friday the 16th of Dec. Amazon has always treated me well. Anyway, I also downloaded the iPhone security key app. When I registered my product code I used the iPhone app to setup my security key; dont ask me why, I just grab the closet device with the security key. Well now if I try to use the physical security key that came with the CE it will not work, only the iPhone app. Anyone have any idea what is going on? Is it a bad device or something totally different?
