I can log in but my screen is in blacks and blues and I cannot see my chat, my spells or anything else. It looks like a Negative. . . . which makes the game UNplayable.
How do I fix this>? I have the current version of DirectX . . . .
That's not a bug it's an issue with your system software/hardware. Post in the support forum instead and you'll have to provide an awful lot more details about said system for anyone to be able to offer advice.
