DC: Re-Sync Error

[Zadevil]

Hi, i have recently installed Dark Crusade on two computers networked together, but once you start a game after about 20 seconds a player is dropped and it says Re-Sync error.

This does not happen on Winter Assault or the original however.

This is the warning log

Any help much appreciated :D
