First of all what is Hai I don't understand that lol.
Are you using hacks?
What hacks are you using?
Do you lag in game?
Do you have a virus on your computer?
It might be your computer or maybe combat arms.
Try to try to reconnect your router. (take the plug out for 10 sec and then reconnect it)
If it still does not work then reinstall combat arms
And btw first post lol
