Normally CSDM module - when is loaded, it works. In Your case there is some problem with loading the module. From that what I can see You does have installed CS addon pack (even if You are saying - no), because You have installed my All-In-One package. The only thing You have changed is - You switched (for some reason) to the regular CSDM from my beta 2.1.2k from All-In-One package. If You are playing with any metamod bots, it's recomended to use my version. Why? Whenever the metamod bot intentionally drops a weapon to pickup another one, the dropped weapon is not removed from the map (AMX X can't hook that because of metamod limitations) and it increases the amount of entities on the server, which is leading to lags, finally to freezing/crashing the server.
I would suggest to reinstall the All-In-One package and update only it with Your plugins and newest beta of podbot mm.
