Theres something wrong with the way youve set this up is all I can think, what game and server do you run? Are you renting a server from a game host?
Funcommands.smx looks missing. There seems to be an issue with sdk tools also.
Are you sure youre running sourcemod
sourcemod-1.3.4-windows.zip
metamod
MM:S 1.8.3, Windows ? Did you add the vdf for metamod?
