Hello Again Dom,
Thank you for letting us know you are using Vista. When the camera is connected via USB, we need to check that it is being seen by the computer. To check this, open up the Device Manager by pressing Start+ Pause Break and go into Hardware, Device Manager. This will identify if the camera is being seen by your computer. You will also want to check and see if you can download directly through Windows Scanner and Camera Wizard. We also need you to try a different card in the camera. You should should be able to download through this method.
I picked up a new "All in One" card reader for my current setup. Pop the card out of the camera and insert it into the card reader and the computer sees it like any other drive. That's what I've done with my previous P&S with a USB 2 reader and now with my DSLR and new reader without a problem. One thing to watch with the reader, some have an issue with particular computer O.S, combo's so test it out well. The one I currently use is a USB 3, it has a problem on an XP computer but works fine on a Windows 7 one, though it could be the USB port type on the computer that was causing the probem.
Good luck, hope it helps.
