Default When flashing new rom, TWRP Giving me "updating partition details" fail message

I updated to TWRP 2.6.3.0 today for toro, and wiped my system, data, and cache. Upon attempting to install CM11's toro nightly from 12/16 I got a "Failed" message.

"Error Flashing zip '/sdcard/cm-11-20131216-NIGHT"
"Updating Partition Details..."
"Failed"

I am unable to install this ROM, and also unable to restore my backup, as I get the same error. Can anyone advise?

Edit - fixed by updating to 2.6.3.2.
