Hey 5rJoud, the Pagan Online team is composed of mostly Serbian devs and a few folks from all around the world - I'm French myself, and we have a few more nationalities, including a couple of talented and dedicated Russian nationals. Whatever the implication is meant to be here with that "russion shet" comment, you're talking to people working hard to make a game, and trying to help you get yours working.
Regarding your issue itself - I wouldn't presume that networking coding is the issue without more info and testing, for which we need more troubleshooting from you. In every case I have personally seen with this issue so far, the Steam client bootstrapper had been killed or didn't launch, hence the issue connecting to Steam. I can't cross that possibility off of the list until we try it. Feel free to pass me the ID of your ticket to customer support by the way, so I can get a full picture of the steps you have already gone through.
