When I got home from school today, I tried to install Modern Warfare 2 (PC version) onto my computer. 
My PC can definitely run the game on recommended requirements.
But it seems that I have to install this game through Steam. Why? No other Call of Duty game has to be installed through Steam, it didn't give me an option not to install through Steam...So I look in the manual, but find no installation instructions.
When it is preparing the game for installing, an error comes up saying that the 'server is too busy'. This was at about 6PM, so I went to Air Cadets and returned at 10PM to find that the servers were still too busy...
Wouldn't it be so much easier just to install the game normally from the disk...If there is a way to do so, please tell me as it would make me very happy.
Thanks in advance.
