no drop the folders into cstrike/addons/sourcemod/
If the package doesnt have folders:
sdkhooks.ext.dll and sdkhooks.ext.so into extension folder
sdkhooks.games.txt into gamdata folder (replace with the one from link below)
sdkhooks.inc into scripting/include folder
youll need to update the gamedata for sdhooks after youve done that
place this #
1027 into cstrike/addon/sourcemod/gamedata/ and overwrite the one in package (unless it was updated in first post, that I dont know)
