@crowgirl you said you already mounted something from the live cd? maybe you have a separate home and root partition, and only the former is encrypted?
if so, I would run
sudo chroot /path/to/mount /bin/bash
to do troubleshooting on the root partition like you would on a powered system. mainly, trying to trace back your steps
never used drive encryption before, so excuse me if I'm lost on the technicalities
