Help with Project Brutality Online

[NikoHatesBowling]

Hello Zandronum community -

I've been diving into Project brutality lately, and i was wondering if i can setup multiplayer. So far, im using ZDL launcher using Zandronum as an engine using these mods -
Feariffic Sprites, sounds, and textures
Project blah blah blah jrmyxd and Hellstorm edition
And the Doom Metal pack v4

Upon launch, i get this error -
Script error, "PB 2.03 Jrmyxd and Hellstorm edition.pk3:melee.txt" line 2252:
"projectilekickback" is an unknown actor property

And yes, i do know that you can use SLADE to edit the text, but i dont want to mess up the .pk3. Is there any work-around?
Also if its any help, these guys pulled it off -

project brutality uses features not present in zandronum 2.1.2, so ull have to use a 3.0 beta: http://zandronum.com/download#betas

alright it launched. Everything seems fine, remapped controls e.t.c. How would i create a server through hamachi? Just start a game and another person with the same mods can connect?
