i think it could be a software glitch as i am having the same problem . the camera window page doesn't always open so it doesn't download... for me,it doesn't matter if i am using the camera/ computer,printer or card reader which is why i am thinking "software" and i have it set to open by default but even when i go into programs and open it it doesn't always open and never the first time), then finally after multiple tries, the camera window opens ( actually it usually is just a blank page with camera window across the top) and i can see the page behind it as it downloads( but i can't select what i want downloaded, it just downloads what ever is new). if you do go to support please post the solution...i was thinking i might have to reinstall the software.
i can download daughters kodak stuff ( different software, same hardware except the camera naturally)
