I can sign in and patch up the beta client, that's all fine (thank god). However, I get told I'm missing the D3DX9_34.dll file (I have directx 10 by the way). So I downloaded the file and placed it in the folder. After doing this it now runs the program, I get to the loading screen and it lasts a few seconds and then it crashes and I get "Authentication error". Anyone know how I can fix this?
