Default [Q] VZW ViperRom 1.6 No Data, cannot change apn

Rooted, s-off vzw m8. After a fresh install I have no network connectivity. I try to alter the default APN but as soon as I change the MCC/MNC numbers the APN disappears from the APN list. This includes any new APN I make as well. Any ideas?

I can use other ROMs just fine, but any time i try to use ViperRom i have no connectivity.

i've tried dirty flashing, clean wipe, and ota updates from older versions. nothing seems to get this working.
