JavaScript Enabled But Error Message

[w513]

Hello, when I first downloaded this script, I received a slot within seconds, unfortunately, I didn't catch it in time. However, ever since then, despite having JavaScript Allowed through Apple Events, I keep receiving this error message:

log "user did not confirm javascript access was enabled. exiting due to insufficient permissions"
end if

I don't know what to do considering it is enabled but it isn't allowing the script to run further. Please advise.

Thank you.
