Missing bullet and muzzle flash meshes

[rroissie]

So I'm fairly certain I've followed the instructions to the tee, but I have quite an annoying problem.  Meshes for certain bullets and muzzle flashes seem to be missing - often people are shooting exclamation marks at each other.  I thought it may be EVE, but as far as I can tell I've installed it correctly.  Does anyone have any experience with this, or am I best off starting over?
