Please help.
Faced the same issue over the weekend. Removed cache, WTF and interface folders. Completely reinstalled the game. Drivers up to date. Pepe hands; almost threw computer out the window.
This morning I logged in and it just suddenly started working with no changes from yesterday.
I guess you just gotta believe hard enough.
Its working now after server under went maintenance on Tuesday. Let me monitor the situation in the mean time, so far so good. cross figures
