[Error] Password Protection: Attempt to call nil?

Alright, I've tried to solve this, but it's very weird to me. I've edited the program startup (when the computer turns on) with this bit of code to password protect my computer:

pullEvent = os.pullEvent
os.pullEvent = os.pullEventRaw -- denies control+T
function clear()
term.clear()
term.setCursorPos(1,1)
end
local password, correct = "", "password"
while password ~= correct do
clear()
print("Please Enter Password.")
term.setCursorPos(1,2)
print("-----------------------------")
term.setCursorPos(1,3)
password = read("*")
if password == correct then
  term.setCursorPos(1,1)
  term.clearLine()
  print("Access Granted")
  sleep(1)
  clear()
else
  term.setCursorPos(1,1)
  term.clearLine()
  print("Incorrect Password.")
  sleep(1)
  term.setCursorPos(1,3)
  term.clearLine()
end
end
os.pullEvent = pullEvent

The weird part is, if I shutdown my computer, then right-click it again, the computer acts as if nothing is wrong. But when I reboot it, I get the error: "reboot:3: attempt to call nil". what do I do?

This is what the reboot program looks like by default in cc 1.46
(in computercraft zip /lua/rom/programs/ )

if term.isColour() then
term.setTextColour( colours.yellow )
end
print( "Goodbye" )
term.setTextColour( colours.white )
sleep( 1 )
os.reboot()

There are no errors on the third line, so maybe you edited the reboot file or something?
Also try: lua
and then enter 'os.reboot'
see if that works.

Yeah, I'm pretty sure that it's a server side error.
I have my own server (I use the tekkit version of computercraft, don't hate me) and it gives me no errors there.

Disregard this post.
