Cannot start gmod server

I’m sorry if this is wrong place for this thread!
So when I open my server start file (.bat file) it gives message box with this information:
srcds.exe - Entry point not found
Procedure entry point SteamInternal_CreateInterface not found dynamic way link library c:\users\xware\desktop\drp\bin\engine.dll.
I have tried to find all around internet how to fix, and I have pasted in same folder steam_api.dll, steamclient.dll, tier0_s.dll and vstdlib_s.dll.
Better contact me here: http://steamcommunity.com/id/sissas5
All help is appreciated!
