Dude,
Stop using VAC Chaos!
It will get you 100% banned!
And if it says it, I don't know why I am so sure that in few days you are going to recieve the following message ,,cheat detected''.
The only thing you can do, it's to stop hacking, maybe you will be lucky.
P.S Wrong section! It will be moved to Help.
as foaieverde says, wrong section, post your questions in the help section next time
to prevent that steam connection error, enable the vac byepass function
