I always forget something I need every time i go away I came to NE to stay for an extended period of time and i left the box for my wireless mouse and keyboard brought the keyboad and mouse but they don't work without the the little box that plugs into the computer so i just went out and bought the cheap ones that just plug in. I don't use that computer much mostly for my sewing machine and use my laptop for this but it is still a pain when you forget something you really need.
my heart goes out to you hope you get it soon..
