Help!

Ok, this is my first face punch thread.
I just got garrys mod yesterday and i’ve tried opening it around 5 times.
But everytime I do so it freezes at the part were this guy’s head is in a cone.
When i open my task manager and close garrys mod a window pops up and says “hl2 has stopped working”
Btw I have Portal and TF2.
Thank you
And what is the “ninja’d” thing all about?

Have you tried restarting steam?

Yea

Ninja’d is said when there is a ninja standing behind the person posting and he does not want to type anything that will anger him.

Gmod needs to load a lot. Did you wait more than 5 minutes?
Ninja’d is when someone posts the same thing as you just before you post it.
