Hi fella's.. Soooo, I've not played DOD for over 2 years now and thought I'd get back into it, so I reinstalled Steam, Gametracker Lite etc. Gone into 'Servers' in GameTracker for DOD and tried to join a game, tried a few and I keep getting a warning message that says 'Unable to launch requested game as it was not detected as installed. Please setup the requested game and try again'?
Now, I can't remember having to do this before, does anyone know what the issue is and what I do to resolve it?
I have tried going into GameTracker Lite/Edit/Add Game and entered the game under 'Select Game' but on the part where it says 'target' I can't seem to work out what file or where it is asking for it from? Is this the reason why I can't launch the game? Can anyone help?

Thanks in advance
