Files Mu Engine season 6 ep3 "Client error new version of game required" help please

Hello, good day to all of you, thank you please read this post, I have the files already configured and all very well but when entering the server with the client to edit tells me I need to download a new version of the game, excuse my ignorance, but someone could take the time to help me finish configuring the server to play? configure the serial! IP and do not understand that really happens, with many clients testing 1.0.4d and nothing, set the common. cfg folder that is in the data / lang / eng something, also set in ConnectServer ServerInfo this, I would greatly appreciate please help me because I have too much time trying to fix it! Thank you.

For every message that you see there is always result how to be fixed, for that are the errors to know how to fix it and what is the problem..
so in your case, you need to configurate server and client version to be 1:1 so in server files you should put like 1.05.20 and in main.exe should be the same for need how to know how to put it there there are editors for main.exe also editors for calculate client version use them , good luck that is how to fix it, if you like it say thanks ;)
