did you add a line in the script you trying to unload

This line:
alias unload { /echo -ae *** Unloaded script ' $+ $2- $+ ' | halt }

and i using mirc 6.03 dont know if that should interfare with the code, just an idea

if ($me != tired) { return } | else { echo -a Get a pot of coffee now $+($me,.) }
