I don't have an answer as to why your camera won't connect with your PC, but using a USB card reader will allow you to access and import the images.
I have a Traveler DC-6900 (Aldi), which is about 5yrs old. It shows that the rechargeable batteries are nearly flat, so I've tried new ones; the same happens. On plugging into my PC via a USB lead, the camera shows batteries are totally flat and turns itself off, so am unable to access my pix via PC. Is this a software problem with the camera? (There are no updates available). My operating system is Windows 7.
