Server Error On Boot up

Well here I am stuck for the first time with my Garry’s Mod Dedicated server. Well to Start Off this is a fresh install of it with a few addons (Qac,ULX). I’ve re-installed the server but it still crashes with the error in the image. The error is being caused by the “tier0.dll” not the “tier0_s.dll” I’ve read the post about the tier0_s.dll said to delete steamclient.dll it dint fix it.
This is the error.

Any Suggestions? Never had this or any issues before.
