ok first of all if you really want help with this problem your going to have to give some kinds of details on it , what its doing and what all you have done ? first of all all the error picture show is that there is a problem and by the looks of it , it looks as though you have not extracted the Data.pk2 from your client and copied and pasted the Data folder into your server folder , the game server requires the extracted Data folder in order for the game manager to read from to tell it what all to load .
