I have attempted to install MetaMod (v1.10.0-hg849) and SourceMod (v1.4.7) for Left 4 Dead 2. Every time I launch the game and attempt to verify the installations, I get unknown command errors. Both mods and the .vdf are located in: C:\Program Files (x86)\Steam\steamapps\common\Left 4 Dead 2\left4dead2\addons.

Any extra information that is needed can be provided.

Thanks in advance.

EDIT: I have searched extensively for an answer, but have found nothing that has worked. The mods simply don't want to install no matter what.
