TJ, when you type your password, no characters or indication appear on the screen to let you know that it's typing. Still, type your password and press return. If you mistype, you'll get an error. If you don't, you'll be returned to a prompt. I've changed the instructions a bit to explain that a bit better.
The instructions (at least step 4) are not designed to get your card to work -- they're designed to get a debug file to our support group so that we can determine the cause of the failure. So far, common failures are things like (•) another software has been installed that takes precedence over PKard, (•) the card reader is not recognized by Mac OS X, (•) the card is not an official CAC or PIV. No matter what the problem, that file will give us a good understanding of the next step to take.
