Its been over 24 hours on my 4 year old windows xp. We have about 1/3 of memory left and the bloody game is only at 74%. At the speed it maintained all night it will take another 10 hours.

You should get a better internet service then. You can also try a download manager:

Also, you should make sure you have 3GB of hard drive space available since those are the minimum requirements to install the game:
