Uninstalling Hazel permanently

Hazel has crashed my computer and I have lot important data.
Now After backing up, I cannot seem to locate several files.
Hazel will not even run anymore. When I try to "OPEN hazel" to uninstall, the thing won't appear or open at all, it's just running on my computer. HOW DO I UNINSTALL THIS GARBAGE?
