Did it get patched? It destroyed my arena character "unknown application error", and i deleted it accidentally pressing the ok button when i tried to load it creating another character :S
I couldnt load my character because that error appeared. Then i created other to load the one i already had and i accidentally deleted it because that error poped out after deleting the new character that used to load my main. I pressed ok and nothing happened (screen freezed?) and i kept clicking, and bb main.
But anyways that error wouldnt disappear. Something went really wrong.
