I host MOHAA on my new Dell computer using Crow King Realism and things have been going along very well...until recently, that is. Someone has been showing up and somehow "hacking" into the game and ruining my game playing ability. Here's what happens: On the Southern France map, my screen turns completely blue and I cannot see or do anything. Everyone else in the game can play without any problems; however, a spinning submarine shows up in the courtyard while they are playing.

Has anyone ever encountered this before and does anyone have any suggestions for me to prevent this from happening?

Any info would be GREATLY appreciated. Thanks!
