So your website barely loads. Can't purchase anything in marketplace. In game is laggy. Whats up? My specs Radeon 7850. I5-3750k. Other stuff decent too. Why? All I wanna know.... Why....
It seems to be a problem everyone else were having [link]. Also there's a known issue were the servers goes on load state which prevents some activities in the game. It happens at a time the fewest users are online. I don't know anything else. If you want deeper input, you should contact developers via a support ticket on the main website, at help link beside your username. Hope it helps.
