Got a CSGO server running on 2k16 that all of a sudden stopped loading Sourcemod and Metamod overnight. meta / sm commands return an unknown command. Tried updating to latest dev builds, no dice. Downgraded to stable builds, no dice. Usually metamod would load even if SM isn't loading, so I'm not sure how to approach this now since mm isn't even loading.

Make sure you are using the windows version.
Try a clean installation with just the latest stable version of meta mod, make sure it's loading and then install the latest stable version of souremod.
