There is a problem to access all files in one go...If you can preview the files on your PC, than select only 5 or 4 to download. Once downloaded, delete these files from your memory card. Continue until you have them all.
I had a customer with the same problem. It is not the camera, Kodak will be very helpful but they will not find any problem, apart from the fact that the memory card is most probably not a genuine one.. .It is your PC. I assume some 40 pictures are on your card, all transferred to the PC will expand them to some 1 GB of data....... .Even if you have the harddisc space available, Bill Gates systems are unable to handle this amount of temporary memory, which in fact is needed.
Use the workaround I told you above...it should do the job..
