Problems with windows live

[Thalaas]

All right I bought Arkham City off steam with all the DLC. Problem is I started a new game with gcox99@hotmail. (With no com on the end, so not a valid email). I played through and could NOT get the DLC to work. Apparently I need a valid email.. and gcox99@hotmail. is not one. So I can't use the DLC. I tried using gcox99@hotmail.com.. but now I have two live accounts. And I don't want to restart another game! Can anyone give me some advice!

Did you register the game to a valid GFWL account? Did you do your playthrough in an online or offline account? DLC can't be accessed with offline accounts.

IIRC setting up the game needs you to register the key to a valid GFWL account. It seems strange that you managed to tie it to an invalid email.

You have to download the Nightwing and Robin DLC through the GFWL client; they're arent automatically installed even though you bought them from Steam.
