Unable to force quit hazel 5 + unable to overwrite with 4

Hello,

After getting push notification to update, I did, to get rid of it. Only to find out dat my licence does not work on 5.
Now that I want to stop 5 in activity monitor it refuses to stop. I think this is also causing the 4.4.5 installation to crash.
I can't restart my computer because its a server and currently in use.
Any ideas?

Hazel 5 is a paid upgrade. The upgrade notice says so and requires you to manually update instead of doing it for you, as it normally does. If you don't want to see the updates, then turn off the updater.
