if you're having problem with "Batman Arkham Asylum" (invalid key product) just contact Warner Bros Games : support@wbgames.com
Just make an email to explain the problem and give them :
a scan of your game book with the activation code
a picture of the box + game book code
the game receipt if you still have it (i didn't...so i gave my GFWL gamer tag)
They will reply to you really quickly (took 1 day for me to solve the problem from the first contact). They will create a support ticket then they will send you a new working code.
Enjoy !
