I've been playing Tropico 4 on the Xbox 360 since release day with no problems. Today when I started it, at the very beginning when it asks to select a storage device, I press the A button to select the main hard drive and the game comes up with an error saying I have NOT selected a device and will have to continue without saving. I've tried numerous times and with other games and this is the only one doing that. I've since transfered all my save files to a thumb drive which the Xbox WILL recognize so all is not lost. I'm just wondering why all of a sudden out of the blue the game won't recognize the main storage device that I've been using for days now. Has anyone else encountered this?
