i receive the message "Cannot creata an instance of the GameCommunication object" when i want to open lobby to play online
can someone help me ?or can send me some servers ip address to play from the game directly without lobby ?

Make sure your version matches the version the host is using.

If you're playing behind a router- you'll need to configure it.

You really should update your game to version 1.12b and play on hyperlobby, anyway. If you want to commit to learning this sim, you're wasting your time in UBi lobby on version 1.02 or older.
