[Q] Beta 6 Fails when installing with TWRP. topic

Basically what the topic says, every time I try installing Beta 6 using TWRP, it'll tell me there's no MD5, a warning that there's no "file_context" (if I remember correctly), and then a red "failed" message after 30-50 seconds. Then I'd have to use my backup file I created before flashing the ROM just to reboot the phone.

And just in case someone asks for what phone/ROM I'm using:

Galaxy Nexus (Toro)
Paranoid Android 3.99

Any idea why this is happening?
