37: IGameEventManager *gameeventmanager = NULL; // game events interface

247: ...!(gameeventmanager = (IGameEventManager *)interfaceFactory(INTERFACEVERSION_GAMEEVENT SMANAGER,NULL)) ||...

272: gameeventmanager->RemoveListener( this ); // make sure we are unloaded from the event system

302: gameeventmanager->AddListener( this, true );

338: gameeventmanager->RemoveListener( this );

Ok, the problem here is that, in your serverplugin_empty.h, on the line that declares your class, you are inheriting IGameEventManager2.

So, when you try and pass the 'this' pointer to functions requiring IGameEventManager (because your gameeventmanager is not 2), it errors.

You should add a 2 to the end of all IGameEventManager's.
