Problem with my disk

I have a legal copy of Mass Effect 1 for PC, but my disk is defective. I have contacted te company that sold it (CDromusa, great customer support BTW), and a replacement is in the mail, unfortunatly, I really wan't to play my game. Is there a site where I could download the game files, and just use my CD key to activate it?

P.S. I know the disk is bad, I have tried the manual install (extract the .RARs manually trick), and ripped the game files using two seperate DVD drives. I even used a whole nother PC to copy the disk to a jump drive, and when I plugged said drive into my box, the comp said there was a error on disk (but only with specific "data" files on board).

I know the replacement will be here eventually, but I doubt replacement disks have priority shipping.

Thanks in advance.
