Skyrocker

Okay, so i completed the game and freeplay gets (kinda) boring to me. so i wanted to play multiplayer, but everytime i try to join a room in multiplayer, there's a error wich says that i can't connect to the IP (or something like that ), and i really want to team up with somebody, does anybody know how i can fix this error?

Please reply to this topic, because i really, really want to play multiplayer.

When i start up the LA mod Emergency 4 freezes, does anyone know how to solve this, because i don't even see the menu

EDIT: Nevermind, i just had to wait a few minutes -,-

Nevermind, i just reached mission 18 so it won't be a problem anymore.

Okay, so i'm at campaign now and i tried to save up money (cuz when i buy equipment, a few minutes later Emergency 4 just shuts off ),

Can anyone help me with this because i really want to do mission 18 but i can't due to this.
