Ключ для Bf3 PE. Проблема со входом через Steam.

For the wrong reason, it stopped running in Bf3, for example, I log in to single via battlelog and requires the game key from me, and the game I bought on steam, where I can't figure out where to view the key on steam, I just haven't tried it, it doesn't work, I log in to my account again, I log in via steam, I log back into the EA network, it requires it again, I go straight through EA, it also requires it, tell me what to do.  

For ENG friends.
