Hi there,
I don't know when this happened but my rules just stopped working. I believe it was after a recent update. I have tried logging in/out. I even re-installed the app.
Only thing I see in log that looks problematic is:
2013-12-02 15:20:00.148 HazelHelper[666] Worker process for folder /Volumes/Data/Converted Movies did not check in.
Thanks for your help,
