Trouble with xmpp4r-simple.rb

Ruby
1

Now, the strange thing about this is that this script used to run just
fine.
Yet, after having run it a few times, for absolutely no reason (No ruby
updates or anything have been executed by me) it has suddenly decided to
stop working.

The following is what the debug returns:

ruby mercutiobot.rb

Exit code: 1

Can anyone tell me why it is suddenly deciding not to work?
