I know there are RAW pictures on the card (a 1 GB SanDisk Ultra II CF), but my computer tells me that there are no pictures. I can see them on my LCD, and Canon's Viewer Utility 1.2 can bring up a preview of them but cannot open them. I have had trouble with the card since I got it (about a month ago), but this is the first time that I cannot find any way to get the pictures off the card (other times I have accessed them via My Computer and simply copied the files into my computer). Is the card defective (and has it been from the beginning)? Is this something that SanDisk's "Lifetime Warranty" should take care of? Thanks for any ideas.
