Having trouble with using the URL.

[RockAndRollMcDonalds]

I found a URL and videos on how to use other for force of will. It seems to have been working for everyone else that has used it. I get an error message telling me it's not valid and needs to end in updatelist.txt. I've checked the link 3 times and it ends in updatelist.txt. I want to see if maybe I have something wrong on my end, so I would appreciate some help. Thank you.
