Do you have any other scripts loaded?

An easy way to tell if you have any other scripts that utilize the same raw events, you should see a line somewhere when you hover over someones nick. If you do see a line, then you'll need to remove the raw events from this script file, and find the other raw events of same numeric, and add the contents from these raws to them at the begining.

If you dont see a line anywhere, and youre not using any other scripts, try using it on a different server.
