You might want to be a little more thorough about HOW your camera connects to your computer or how it reads the camera media.. Is it USB (ver 1.1 or 2.0), a card reader, a mini CD for example.. You might check to see if any other hardware devices that connect the same way fail as well.. There are usually a couple of ways to get pix from a camera.. One is by connecting the camera itself to a firewire or USB and read the media while its in the camera OR remove the media and read it via a media reader or CD rom drive if its a mini CD media.. In any case, there are 2 ways to get to the data on the media. So did ya try the other way? It may not be a total loss.
Good Luck! Lynlee
