I have a Canon Rebel XT. I asked for, and got, a bigger card for my birthday. My ILs got it for me, and they got me one that is a faster speed. It's 2GB 133x Speed, Lexar Professional.

But when I put it in, my pictures are all blurry. I took a pic with the new card, then put my old card back in and took a pic, and sure enough, they're blurry.

WHY? Is there something I can change? I've already opened it all up and everything, thought I could sell it I'm sure. It's so frustrating, but I figure maybe I'm just missing something easy. Anyone know?
