GMOD Effects issue

Lol I keep on getting this error when I use sweps with weapon effects such as fire, and the strider warpy thingy(I am using steam version :U).
Oh, and heres the console error;
Warning: Unhandled usermessage ‘DrawHitSmoke’
and some few other messages

Sometimes I can’t see the blood either. :S

Bump, help, its annoying the shit outa me :[
