Very annoying error

When I run the server using clubs source it works fine until I press play. Once I press play, in Wserver.exe it says client trying to connect. Then it shows a infinite loading screen. I tryed to add a map to the game and i was wondering if someone could help? The tutorial I used was Trappeds tutorial on how to add a map to the server.

Yet again, another annoying post by this guy

And he wants to make a server with developers and apparently he is the only person who is developing the server and he knows c#...

Doubt that claim. As far as I am concerned, the only developers of his server is MPGH and not him
