See post #2 for the short answer.
Now for the cause:
You flashed an unlocked bootloader rom on a locked bootloader phone. The stock recovery you have access to will only flash signed roms from Motorola and you can't replace it with CWM until you've unlocked the phone. Like post 2 said, download MythTools and have it get you back to stock, say yes to using stock recovery, then either root it and do what you were doing or unlock it, install Philz CWM, and start using the custom roms. For RSD to work for you right now, extract the fastboot, open up the xml file, and delete the two lines with -- <step operation="oem" -- in them.
FWIW, we should have an actual KitKat update sometime eventually soon and that will contain a fix to prevent the bootloader from being unlocked. If you don't unlock the bootloader before that update you probably never will.
This is for Bell ICS stock. You have to use ATT JB fastboot's xml, don't copy/paste this -- the md5sums are different but the changes are the same. The lines to remove are in bold.
