Are you sure you installed MM & SM correctly?

If you RCON "meta list" is should return something like this:
Listing 4 plugins:
[01] SourceMod (1.4.0-dev) by AlliedModders LLC
[02] TF2 Tools (1.4.0-dev) by AlliedModders LLC
[03] BinTools (1.4.0-dev) by AlliedModders LLC
[04] SDK Tools (1.4.0-dev) by AlliedModders LLC

This will let you know if these 2 are working. Also note that the recent TF2 updates have broken SM & MM so you may have everything working but the plugin itself may be having issues with your version of SM and/or MM. Lastly you shouldn't have to re-install your TF2 server because of issues with either of these mods. You could just delete the addons folder and the sourcemod cfg folder, then re-upload.
