I have a very old setup file of Counter Strike: Condition Zero game which someone gave me about 14 years ago. It always worked perfectly. But recently, it started causing problems when my laptop is connected to Internet. I tried to find solutions but they didn't work.
The exact problem is: When I launch the game when Internet is connected, the game home screen freezes, the intro music keeps running and I've to force quit the game from Task Manager. And it shows an error something like Half-Life launcher is not responding.
But if my Internet is disconnected and I launch any of the games (Condition Zero or Counter Strike 1.6), it launches successfully and I can connect to Internet again, the game doesn't get affected.
Now, I really don't need Internet as I just play Condition Zero Tour of Duties only which are offline missions.
So is there any way to stop interacting this game with Internet at all? Can it be blocked for just this one program? So that I don't have to turn off the Internet just to launch the game.
Thanks.
