I received a CannonSD450 digital camera, downloaded the program, when I hook up the camera to continue installation it tells me I don't have a connection with the camera. I've spoken with the techs at Cannon (for an hour), at first they said something about PTP (Photo Transfer Protocol), they couldn't find a download for WindowsXP, then something popped up and said I wasn't the administrator (I am), they said MAYBE a spy was fighting with me. I've tried to contact Microsoft and Dell - a waste of time. Everything else loaded into the computer when I downloaded the cd but I can't make the camera connection. Does anyone have a clue as to why this is happening? Thanks for any suggestions.
