Was the camera new or secondhand. It may be you have an earlier version of the software. You can download the latest version from the Canon web site, that may help.
However to be honest loading images via the camera will take a while, you're better off buying a card reader, much quicker and safer, as it doesn't require the camera to be powered up. You don't want the battery dying on you half way through a download. On the plus side the batteries in the 1D/1Ds seem to last for ever!!
Just checked, The software for my 1Ds lll is V16. I'm sure the 1D will be similar
