I emailed you about this but it appears you didn't receive it.
First thing is to make sure the HazelHelper process is running. You can check using Activity Monitor, located in /Applications/Utilties. If it isn't running, quit System Preferences then restart and load Hazel.
If it is running and still not working, click the "View Log" button in the "Info" pane and let me know if you see any errors there.
On a side note, if you mail in to support and don't receive a response, make sure to check your junk mail folder/filters. I try and respond to every support email that comes in and while it's possible that I may miss one, it should be a rare occurrence. Also, if you do find the email in your junk/spam folder, please mark it as not spam/not junk to train the filters for future emails from me. Thanks.
