orcishgamer: If no one told you, you just fire up The Dark Crusade and enter the CD keys from the other two (downloadable copies sometimes hide these in your registry, Steam used to be terrible about this, I had to hunt his keys down for his Steam copy for him) and it unlocks all the races. You can just play any race on the world map then (or multiplayer).
MonstaMunch: Sorry to go off topic, but perhaps you could help?
I finished downloading Dawn of War Platinum Edition yesterday. Initially it asked me if i wanted to register Dawn of War + Winter Assault, or The Dark Crusade. I selected Dawn of War + Winter Assault and registered them without any issue. Then I was going to register Dark Crusade, but could no longer find anywhere to register or even run it. There was nothing obviously marked as Dark Crusade in the main folder where dawn of war had been installed to.
Any thoughts?
Hmm, I bought separate boxed copies (Gold which is DoW and Winter Assault and another of TDC), I suspect you possibly didn't install it (if you can play Necrons of Tau you are playing it, I should add) and need to rerun whatever installer you have. I owned multiple copies of each before Platinum box ever came out so I might be a bad one to ask, it may work differently than I was assuming:(
However, you'd likely look for a whole separate install of TDC, that's the final one (before Soulstorm).
