Sorry, my crystal ball is at the shop being repaired and I don't know 
what "an error" means or how to fix it.

Please COPY AND PASTE the full text of the error, starting with the 
line "Traceback" and ending with the error message. Don't summarise it, 
or re-type it from memory.

The Python interpreter provides a lot of useful debugging information in 
these tracebacks. If you ignore it, and just say "An error occurred", it 
is impossible to tell what the error is and why it happened. Your code 
has over 20 lines in it. Assuming a minimum of ten things could go wrong 
with each line, that's 200 possible errors. At minimum.

It is a waste of my time, and confusing for you, to try to guess which 
of those is the error, when you have the information right there in 
front of you.

If you post the actual Traceback, we can help. If you don't, we can't.

Have you tried googling for "daemon"?

In summary, and Ben will correct me if I'm wrong, a daemon is a computer 
program that runs as a background task. If you come from Windows, think 
of your anti-virus scanner which scans every file when you double-click 
on it, before the file runs. That will probably be a daemon, or the 
closest equivalent.
