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?
