Stupid camera

I think that I am destined to have bad bad luck with digital cameras. So today I was totally wanting to have new pictures of the kids and took tons of pictures. Half way through downloading them, my computer says they dont have the correct "parameter", whatever that means and erased them, not on my computer or my memory card-dumb! Then I put the card back in the camera and it says "card is unreadable" what the heck does that mean, I've been taking tons of pictures with this memory card. Are you kidding me? Then my camera totally shut down and I cant even get it to turn off completely. Oh it won't work black screen nothing but it's still open. It didn't say the batteries were low or nothing. Stupid Camera. With that said on to my next blog containing the pictures I saved!
