Hi I am having a problem playing the game unfortunetly everytime I try to play I get the message, unable to connect to login world. I have done everything I can think of to solve this problem, I have run as an administrator, created a shortcut to bypass the website and turned off firewall and antivirus, still no luck. I am trying to play this game on a public network but I checked and it says that dragon nest is allowed on public networks. Does anyone know how to get past this error message so that I can play this game, Thanks
