So yeah, 3 script files loaded. Try this...
Paste the script at the very top of your script window.
If it doesn't work, remove it and go the the next script (Alt+R > View)
Paste it at the top again and repeat.
If it *does* start to work, you'll at least know which of those scripts is the guilty party (and can maybe do something about it).
P.S. You *are* aware of the fact you can't trigger remote scripts yourself (meaning from the same running client)?
