OK, I am in serious need of help. Everything else has gone off without a hitch, except when I run the installer, it hangs up 100% of the time on:
...
Checking for MD5 file..
Skipping MD5 check: no MD5 file found.
Starting AROMA Installer version 2.70RCs

The entire system locks up and I have to do a battery pull since I held the button for over a minute and it never shut down.

I have wiped the drive multiple times, doing factory resets, Dalvik and normal caches, and data. I've deleted and redone partitions.
I have verified the checksum multiple times as I did multiple downloads of it.
If I do "Zip file signature verification." and press Swipe to Confirm Flash, this is the result:
...
Installing '/external_sd/ROMs/Hyperdrive RLS3.1 KK Note 3.zip'...
Checking for MD5 file..
Skipping MD5 check: no MD5 file found.
Verifying zip signature...
E:Zip signature verification failed: 1
Error flashing zip '/external_sd/ROMs/Hyperdrive RLS 3.1 KK Note 3.zip


I am running Safestrap 3.72 - the beta for Kit Kat.
BusyBox is installed and updated and has been opened.
I'm on NC4. I couldn't find a NC5 firmware to flash.

Edit:
I deleted the prior file and put another one on and flashed it. Install said successful, but when it boots it sits at a black screen and I have to do a battery pull. Now it just sits at a black screen after indicating a successful install to ram-slot 1. The LED is off.
