gmod 9.0.4 LAN

[warlord7856]

hi, sorry to be a bother, but does anyone know how I can play garrys mod 9.0.4 on a LAN, because i downloaded a 9.0.4 dedicated server and set the server up, but every time i try to join it it says im running a different version of garrys mod to the server (and im not). Thanks in advance for any replies.
