guys, I am having great difficulty. in the options menu of the game Call of Duty MW3 have the option to login to Facebook, right? then .. I marked the option to enabled, but when I click under where it says: Login With Facebook - appears the error: Login Failed. Please re-enter your account details. What should I do to be solving this error?

thank you!

I did not find any option that I can be re-setting my email and Facebook password!
