Hazel worked on first run but no longer works

Hey
I set up a couple of rules that I ran and which worked great but now they aren't working automatically or manually.
How do I fix this? Also when Hazel does run automatically does it run the very instant something meets the criteria or is it based on a shedule?
Thanks in advance!
