Ok, finally its time to remove Dark Crusade and leave only Soulstorm in there. However, you will realized that in Multiplayer you can only play Dark Eldars or Sisters of Battle. To have the rest of the race, you just have to install the following :
I stress again that you will still need to have legit version of Dawn of War, Winter Assault and Dark Crusade forthe CD-KEY. This software will not give you keys for that. It just helps you save some space by removing those software away.
If you uninstall Soulstorm someday, just uninstall this software as well to remove away the keys and extra files it has placed in your computer.
