No hazel, no fun

Hi there,
Since a while ago (sorry, can't be more precise than that) Hazel won't run on my system. There's no Hazel pref panel any more, and trying to start it using quicksilver gives me an error stating that the pref panel "(null)" can't be started. There's no hazel process in activity monitor either (so far I can see).
Any way to fix this? I currently run Snow Leopard, by the way; upgraded just last week.
