both day 4 and 5 are completely free. when you download a game on itch.io it gives you the suggestion to tip the creator and i think that's what you did. instead of choosing to leave a tip, you can click " no thanks, just take me to the downloads" right above the tip amount box

while the creator suggests deleting your saves and app data before downloading each new update, I personally find it unnecessary most of the time, if you don’t mind a bug or 2, unless you have accidentally clicked that you’re under 18. Try downloading the newest update and see if it work, if not I can tell you how to delete everything
