Download client version 0.15.12 preferable a original client not any pserver because from a pserver it might not work cuz the admin might have changed the ip.Open notepad and write that in it then save it as launcher.bat make sure its .bat.Edit the ip 127.0.0.1 to ur ip and then start it
Code:
start .\release\DRAGONICA.EXE /NoGsm /LaunchByLauncher /ServerAddr:""127.0.0.1"" /ServerPort:""11201"" /SiteName:""My Dragonica""
exit
