Hey guy's! Just picked up a 360 yesterday and was setting everything up with only one problem so far. I installed the software from www.xbox.com/pcsetup and when selecting pictures/music I can access my computer without a problem. How ever, when I click on the media center icon it takes me to a screen that detects the computer and then gives me my security key. I then click next and it sits on a screen that says "install the software at xbox.com/pcsetup and enter the security key when asked" Well the software is installed and I have no idea where I can enter that key. The software itself see's the xbox, the pictures/music sees it. But the media center wont let me go past that screen (the a button is greyed out) Any ideas on how to enter this key and get past that screen? I'm a 360 noob but I know pc's fairly well and i'm lost.
