Is there a faster 3rd party download of MW available?

Hi,

Just wondering if anyone knows of (or even if it’s possible) a 3rd party download of MW that isn’t massively restricted on download speed? Can we download elsewhere and then point Battle.net to the download? I’ve been playing a while and this evening the game has decided it needs to be reinstalled but the speed of the download means it is going to take a couple of days!
