Blocked sight.

Hello.

My problem is that the DD (HOLOGRAPHIC) sight for the AKS-74U is blocked. I'm meeting the requirements for unlocking it. I've had this situation for at least a month now and I can't do anything about it. So far I've tried playing a full match in various modes, including the portal, because it helped once before, I've used the "repair" option in EAapp, I've cleared the EAapp and game cache (C:\Users\***\AppData\Local\BattlefieldGameData.kin-release.Win32) and the sight is still blocked. I've also written to support but they're send me here ;)

Maybe you can come up with something.

Thanks and best regards ;)
