EA StaffHi love999cats,
It seems like you don't have Battlefield 3 on your account. Please make sure that you are logged in with the correct Origin account and if you are playing on console, that your Gamertag is properly linked to your Origin account.

If you have been playing Battlefield 3 at all, your account is already linked. It is a matter of figuring out which email address you linked it to. If you cannot do this yourself, might want to get in touch with EA at help.ea.com
Look. Quite long time ago I've had a PSN account called Spywere_2012. Then I deleted it, but my Origin account was stiil called by this name. When I logged into Battlelog, with new PSN email and password, BL showed me not existing profile, Spywere_2012. Later, after I saw something's wrong, I've changed my name on Origin - now it's called love999cats (this is correct and existing PSN nickname). When I logged in Battlelog again, there was my profile with nick love999cats, but nothing changed. I do not see my Battle feed and soldiers. (It's a bit complicated and I don't know what to do now.)
EA StaffHi again,
If you need further assistance linking your PSN with your Origin account, then please contact a Game Advisor via this link: http://help.ea.com/contact-us
Select Battlefield 3 as the Product, Account as the Category and PS3 as the Platform. Additional contact options besides Answer HQ should be available, if not, please try again at a later time.
Thanks.
