flash card problems

[Paul Stenquist]

My *ist D arrived today, but I've been unable to get it to work. It 
won't recognize my flash card. It's a Lexar 1gig CF+ write accelerated 
card. I was going to try to upload the firmware update before doing 
anything else. I was able to load the firmware update onto the flash 
card in my Mac. When I turn the camera on with the memory button held 
down, it displays "version 1.00" as it should, then the screen switches 
to "Memory Card Error." I get the same message if I just turn the 
camera on without holding down the button. I reformatted the card on my 
computer. No change. I tried going to format on the camera menu. If I 
tell it to proceed with the format it again says, "Memory Card Error." 
Any clues? I've contacted Lexar tech, but I don't know how long it will 
be before I get an answer.
