[Q] Perpetual "System UI has stopped working" message after changing boot animation topic

After changing the boot animation on my Moto X by using Matthew Pierces program Mbat my phone perpetually receives the message "unfortunately, the process com.android.systemui has stopped" on startup. If I select Ok the message reappears shortly and prevents me from using my phone for more than a few seconds. When I tried to revert to stock boot animation using the program, the program tells me rm failed for /data/moodle/bootanimation.zip Any help on how to fix this???? Thanks
