I have tried Drowlys private server but when I try to open server.exe in Private Server\server\bin\Debug it gives me this error:
Unhandled Exception: System.Net.HttpListenerException: Access is denied
at System.Net.HttpListener.AddAllPrefixes()
at System.Net.HttpListener.Start()
at server.Program.Main(String[] args) in C:\rotmg_svr-master\server\Program.cs:line 26

PLEASE HELP! I want to play a private server really bad!
