is there any way to join my own game? tried agian and agian even making on a different computer!!!!

Yes, but why would you want to?

CardBoard i join my own game...

Please describe why you cant join your own game.

I can deduct that you are running the dedicated server built-in soldat.exe (Using soldat.exe -dedicated). To join your own server, you have to download the dedicated server as a stand alone version, at http://www.soldat.pl/down-s.html. For more information on running a server, refer to http://www.soldatforums.com/topic.asp?topic_id=18763
