What I'm asking now from you, the experienced folks, is which browser to use amd how to set it up (maybe some settings are blocking the connection). Tried on Chrome, Firefox, Opera, Safari for Wndows and Internet Explorer. Trying to fix this problem and get in touch with EA, I found out that Live Chat doesn't work. I have the serial key, the steam receipt, order number.everything. Which ever case may be I'm 100% I can't fix this problem on my end and buying a game that I already bought seems pretty unfair to me. yeah keep sending them tickets and someone will eventually give you your key. Thats how i got it, just keep sending them requests until someone competent replies. I have 2 guesses: 1.somehow, the serial key can be used on a limited number of machines, note: back in 2010 I had a different PCĢ my data got lost when EA introduced Origin I just subscribed this with EA play and i dont know where is the serial key so i cant play multiplayer. Statement that I agree to, the person using the serial key being me back in 2010. When I write the serial key it says that "this serial key is already in use". I'm using the same EA account I used back in 2010 but it requests the Serial Key (which is glued to my steam account, obviously). I'm launching the game through steam and after that, i have to log in with my EA account to be able to play multyplayer. I bought a digital copy via Steam, so the game is in my steam library and has always been. Even so, I was unable to resolve my issue that I had last year and if you end up with the same problem, I dont have a solution. When I enter the EA app, the game does not appear in the library, although my steam account is connected. but when I right click on the game in the library, I cant find the key. When I click on the multiplayer option, it asks me to enter the serial key. Information, Guides and Announcements for the EA app You have two options, you can either press shift+tab in game and click on the CD key button to get a pop up with it, or you can right click on the game title in your library and select product key from the mini menu. I bought Battlefield: Bad Company 2 on Steam.
