[Q] Titanium Backup encryption killed me

After finishing a clean install of JB and restoring my apps, all was working perfectly on my Maxx. I have used TiBu Pro for a couple years, but I've never used its encryption feature. Now that I'm on JB, I thought it might be worth a try, so I enabled it, then rebooted into recovery, then ran a fresh nandroid backup. It completed correctly, but when it rebooted afterward I got an error message that the encryption failed and I needed to do another factory reset to be able to use my phone again.

While that's certainly a crap deal, I wasn't too upset since I'd (literally) just finished a new nandroid, so I figured I'd do the reset, restore the nandroid, then disable encryption again and be on my way. No dice.

When I hit the button to start the reset, it just reboots back to the same error every time. If I boot into the on-board recovery panel (the one with the white letters) and try to go into recovery mode from there, it only boots into the dead Android robot with the "!".

I looked at TiBu's website and tried contacting TiBu, but have found no useful information yet. Has anyone else experienced this? Got any ideas on how to recovery this thing or break out of the cycle I'm stuck in?

Thanks!

***UPDATE***
Here are some more details to see if anyone else can help me work through this. I can only get to two possible reboot states at the moment. The first (when attempting a normal startup) boots through the initial boot image, then the first part of the boot animation. I see the red eye for a few seconds, then I get:

Encryption Unsuccessful
Encryption was interrupted and can't complete. As a result, the data on your phone is no longer accessible.

To resume using your phone, you need to perform a factory reset. When you set up your phone after the reset, you'll have an opportunity to restore any data that was backed up to your Google Account.
Then there's a button that says "Reset phone" at the bottom (this is what makes me think the TiBu encryption is the culprit). If I hit that button, it just reboots to the same error every time.

The second reboot state is if I power down the phone completely, then boot into recovery by holding the Up/Down volume buttons and Power button for about 3 seconds. I get a black background with white text that says:

Boot Mode Selection Menu (0A.77)
Vol Up Selects, Vol down Scrolls

Available Boot Modes:
Normal Powerup
Recovery
AP Fastboot
BP SBF Flash
BP Only
BP HW Diag & Root AP
BP Tools
If I try "Normal Powerup" I circle back to the first reboot state. If I try "Recovery" then it goes to the picture of the Android robot keeled over with a red "!" in his chest and I have to manually reboot it again.

I'm thinking that I might need to go to the "BP SBF Flash" mode and try to SBF back to the .211 file that's still on my sdcard, but it's just a guess (and, admittedly, the only other option I can think of that's even available at this point).

Anyone have any thoughts?

***UPDATE #2***
By pressing both the volume up/down buttons at the dead Android robot, I've now accessed the recovery menu I'm used to seeing (when doing nandroid backups) that lets me perform the factory reset. Unfortunately, doing the factory reset doesn't change anything, and I still boot up to the encryption unsuccessful message.
