Stop pretending the levels are bugged when the problems comes from you, please
This level is working as a charm and the file is accessible, so if you are on a “error accessing resource” then it means you’re not on the right directory
Keep on trying things until you get something different from what you’ve already got from your different attempts, that will be the answer ( I hope! )
Anyway, if you’re still struggling too much on this one, feel free to post a message there ( please, avoid spoilers ( if you wanna talk about spoilers, PM me ;) )).
Good luck!
