Custom blood particles not working, worked before latest update

I have installed blood particles before (because the vanilla blood just isn’t satisfactory) and it has worked, but since one of the latest updates I get TF2 style blood instead of the vanilla or the blood I have installed. I have tried uninstalling my custom blood, but I still get the TF2 blood. I’m guessing it was a source update and may even be unfix able by garry or anyone, so should I even consider dropping it directly into the GCF?
