Thanks, Jim, but that page, unfortunately, wasn't much help. Under Devices & Options, Microsoft MCE, HID and USB-UIRT are all checked and they all have (Active) behind them. So how come I get the above errors when pressing Next to enter the wizard or try adding a blaster command?
And I find no information anywhere if it is possible to map a keyboard shortcut to a blaster command. If I want to control my receiver with my IR remote, I just aim it at the receiver! What I want to do is control my receiver and sat box from another room through MC using my bluetooth keyboard (or preferrably Gizmo if that functionality is added to it sometime in the future). My PC and the USB-UIRT are next to my receiver and sat box in my home theater, and my TV is in my living room.
