[paulo_crash]

I downloaded the latest version located at this link: http://users.alliedmods.net/~kyles/builds/SteamWorks/ (Linux)

But it is giving the following error:

[17] <FAILED> file "steamtools.ext.so": /home/ogp/OGP_User_Files/whmcs/670/csgo/addons/sourcemod/extensions/steamtools.ext.so: cannot open shared object file: No such file or directory

The server would be from CSGO.

What could it be, how can I correct it?
