Ok so I followed the link on the download page and did the download, on mozilla firefox on windows 7.
I ended up with this file in my download folder: DOExpanded2FIXED (which is an RAR file) - I have no idea what this means.
I try to run it and it just opens Dawn of War: Winter Assault (in properties the game is told to run using this other game??)
Any idea how to actually play Dark Omen?? Or did I somehow download the wrong file / not set it up right? Thanks.
