I'm in the Wild Lands attempting to rescue Wilbur. Can't read the note or give it to the merchant to win the numbers game and get the magic stone. Need to win the archery challenge.
Does anyone know what the problem might be.

A quick google for your question:

shows two threads that might help:

Did you try right clicking on the note? Does that work?

Just a fyi, the subforum for that game series is located here:

https://www.gog.com/forum/the_book_of_unwritten_tales_series

It's linked to on the right side of the game's sales page:

...only if you use Barefoot Essentials.

Oh is it? Sorry about that. Thought it was built into the website.

Just for reference, we're talking about a Grease Monkey script for this website:

reedit: But to go back to which forum for which game:

Front page of the forums:

Look towards the bottom left for a list of games supported here. I searched for 'unwritten' and it came right up.

Hope this helps. :)
