OMG! You got a GREAT camera.
It may be too large for your camera to transfer it to the computer, maybe you need a card reader. From my camera to my computer I can only use a 32 meg. Anything larger has to go in the card reader or the card reader in my printer. I have a 128 and a 64 also. And the 8 that came with the camera. Only the 8 will transfer to the computer. And another bad thing about my camera (HP) is that 128 is as big as it will hold. Glad I didn't buy larger. I thought HP would be great since I had HP computer and printer. NOT..........
