Query: Loss of data!

I purchased this camera, a card, and a card reader. I initially had difficulty connecting the camera to my computer, and when I finally was able (using a usb cable and not the card reader)discovered a bunch of corrupted data. I thought it must be the card. I replaced the card, things seemed fine for a while, but it recently happened again. I have to assume it's the camera, or the provided usb cable. Either way I have no means of transferring files without the fear that I'm going to lose pictures of my kids.
