Rome:total war Multiplayer? - no prior install of rome total war found

Hey guys, bought Rome: Total War off steam let off, download and install the entire contents, etc. .. Determine Made some very personal struggles, hard and decided I wanted to play some multiplayer, the problem is that I can not get the damn job if you try the patch I have from the website the message "No d install" prior installation of Rome: Total War was found. This facility will be terminated. "

I tried to connect without the fix, but it simply says "login failed" After I typed the code I have.

Any help would be appreciated, thank you:)
