How do i change the explode effect?

i downloaded http://www.garrysmod.org/downloads/?a=view&id=120123 And write \orangebox\garrysmod\lua\gmod.lua

[lua]
resource.AddFile(“particles/vman_explosion.pcf”)
resource.AddFile(“particles/particles_manifest.txt”) – I don’t know if this is needed, oh well .

PrecacheParticleSystem(“dusty_explosion_rockets”) – Optional if you don’t want the lag I always get when spawning unprecached particles :c
[/lua]

But seems to be not worked. And The jihad (ttt swep) not worked too since i added New Explosion Effect.

If i use Jihad , It marks [Attempted to create unknown particle system type “dusty_explosion_rockets”!] to the console , And not appears explode effects just player die…

anyone?

It will only work on non SE servers D:

Excuse me , What is that means SE servers?
