Particle help - Particles do not work on HL2 at all?

I’m having big issues with particles in HL2. they just, aren’t working at all!

Here are the screenshots of my setup for particles:

https://dl.dropboxusercontent.com/u/3922896/Particles2.png (in-game tools)

And here is the particle itself: https://dl.dropboxusercontent.com/u/3922896/GrowlerlandParticles.pcf

particle_manifest itself does not work, as it is overwritten by the VPK, or so I hear.
Am I missing something here? can someone help me? X_X

Make particle system face the ground

if that’s the case for if the particle works, then I’ll do that for sure.

that said, as you can see in the console, it isn’t even picking up the particle. it isn’t detecting it at all.
This, I assume, is due to the steampipe update.
