Forums Scripts & Popups $read command not finding file

I own the Skeleton_in_the_Closet dicebot, based off the Dem Bones/Bone Devil code. One of the commands in the file tells the bot to search a crit table and randomly display a message from the file. However, no matter where I place the file, he's not seeing it! He's been offline for a couple years, but it worked fine before.

Relevant code:

; nifty little critical strike table; reads numbered lines from text based on d100 result.
on *:text:!crit*:#: {
set %crit.roll $rand(1,100)
msg $chan ( $+ $nick $+ ) $read(crit-table.txt, %crit.roll) }
unset %crit.roll
}

Where should I be moving crit-table.txt to so he'll actually see it?
