My friend was using the same hack I ws trying to use while I was trying to get it to work.
And VAC2 hasn't even been released yet.
Edit
Also, I am playing CS 1.6, and it will crash no matter what hack I use.
I'm trying to run an ESP hack, but when I startup CS, it starts to load then crashes.
This same hack used to work for my in the past, and it works for my friend.
What settings could be causing this?
