Query: Invaild Product Key

The game was installing fine until i tried to input the product key which worked at first but as soon as i run the game and try to login into my GFWL (i used my XBL account) account....it says "invaild product key." I have never been so disappointed in a product such as this one. Absolutely disgraceful for a game that i pay money for and it doesnt even work!!
