Lightroom: Can't import pictures from CF card
I am traveling to shoot photos at my niece's wedding and all of a sudden my Lightroom won't let me import any pictures off my CF cards. I have used 3 different cards, in a reader that has allowed me to copy to the desktop, but when I try to import into Lightroom I get a message that says, "The following files were not imported because they could not be read" I am using a Canon 10D, 5D and 1D iv and nothing works. It all worked a few days ago. I just downloaded Lightroom 3.5, I had 3.3, but that has made no difference. The wedding is in 2 days and I'm ready to panic. Any thoughts what I might try?
