Dear,
I logged in successfully in game and go to Nula for my mission, after i finished at teleportman, in Nula could not see my character and i was kicked out of game and exited to main window. I tried to open and there is the the warning "patchserverlist empty (errorcode: NEF12150)", i tried and try but could not even i uninstalled the game and download new one links from Z8games.com. Installed successfully, but when i lick on the icon at deskstop it is the same problem.
