Guys stop messing with your PCs.
DLC are not working for anyone: (Dragon Teeth, Second Assault, China Raising, Final Stand).
IT"S NOT YOUR PC, IT's EA Servers. They unplugged the BF4 servers for PS and XBOX on Nov 7 and people started reporting this mess.
On many servers people complain that they have to re-unlock weapons they unlocked years ago (even having 5 service stars with that weapon).
It's not registry, it's not DirectX it's just EA.
EA Support says that they are escalating this to management. Please be calm and wait, we cannot do anything.
If they want to further trash BF4 hoping to retain customers for the future they will be a lot disappointed.
PC servers for BF3 and BF4 are the only FPS game for hundreds (if not thousands) people. If they do mess with BF4 there will be no way back for EA.
BEWARE EA, if you do not fix this issue within the weekend, you will jeopardize the campaign for your newer BF on which you are working on. BEWARE!!
