Are you downloading a PServer that comes with "rotmg-svr-master"/"_Server", or is it just the client?
1.) If you downloaded a P-Server with server files (rotmg-svr-master or _Server):
Navigate to rotmg-svr-master/server/bin/Release (or Debug, depending on what PServer you have) and run server.exe as Administrator.
If it says "Listening on port (number)..." then it is working.
Also navigate to rotmg-svr-master/WServer/bin/Release (or Debug!) and run WServer.exe as Administrator.
If it says "Listening on port (number)" and spams "Not supported type:Merchant!" then it is working.
Finally, run the client.
2.) If you downloaded a standalone client:
Check to see if the server requires Whitelisting, Hamachi, or is down.
