Okay, so I did everything that the guide said to for the guns to knife.
I used HxD, and I looked up pv-m4a1.ltb.
I changed the "0" into a c which turned the "30" into a "63" just like in the guide.
After that, I replaced the old .rez with the modified .rez, and started crossfire.
It loaded fine, no X-Trap errors whatsoever. However, when I try to enter a game, it shows me a black screen with an xm1014, 0:00 on the clock, and a minimap with nothing on it. Shortly after, I am kicked into the lobby. Can someone help me?
