I cannot teleport to a region - teleport stops on the loading world and logs me out, if I try to log in on that land directly - loading stuborns on the same point. What could I do? I tried to reinstal the viewer, I tried to log on another computer - nothing helps. On another account everything works correctly. I'm not banned from there for sure. The communicate after logout says: "Disconnection with the region has occurred".
