Okay, so I'm currently starting to get really pissed of at this dysfunctional process of getting a security key. I have downloaded the app and logged in on my account on the website, I typed in the serial number given on the computer into the phone. Then, when I write in the security key from the phone to the computer, this comes up: Sorry, we couldn't find your serial number. Try again? Does anybody know how to solve this mess? I really want the perks you get from having a security key. I have tried several times to uninstall the app and re-log in to retstart the process, but it doesn't *********** work. I'm starting to lose my gosh darn patience with this... I have tried to make contact with the useless customer service at EA, but I can't find out how the **** I get hold of them; it's such a sprawling mess of websites that don't give any answers. Would be easier to make contact with my dead ancestors' spirits through an oujia board. If anybody knows anything about how to solve this I would be endlessly thankful.
