Dawn of War Codex

Anyone know what this is/how to fix it? I just had a game with [FEG] Venjitron hosting and my team was doing so well with Ordo Malleus, but just at the climax, right before I could deploy my paladins I got this shit and had to restart the game. What the hell do I do about this? I don't want to get a reputation as a leaver

It's hard to say, some people have sworn by certain window versions/updates.

Either way, people are very understanding about this sort of thing. I wouldn't worry about your reputation!
