itch.io

I purchased Fallen and have an older version of the PDFs so I would like to update to the newly released version but I cannot find a link to do that. Would someone be so kind as to let me know how to update games purchase on itch.io? Thanks.

I purchased this excellent game from Ratti Incantati and received the physical copy and the PDF version. How do I get it linked to itch.io to show that I have purchased it? I'd like to add the fillable character sheet. Does this get purchased separately?
