Hi. When i click dark messiah multiplayer nothing happens even when i click it on the menu please help.

Hi. You must register and download the game via Steam. Your computer must comply to the system requirements, you must have cabled broadband and no software (firewall) blocking online multiplayer.
For more details see Dark Messiah Installation and Troubleshooting Instructions.

I have already got an account for steam.What are the requirements?I will check firewall

I disabled firewall but that didn't work.

Hey, I have an account and everything, i have the system requirements and everything but when i double click on the icon nothing happens.

Hi , I have the same problem.
Single player runs fine, but when I try to start multiplayer with steam.
it says launching game and then nothing happens

Yeah the same thing happens to me aswell

Does anyone know wot this error is called or how it happens?
