I have purchased the game before and did not have an account I cant update because I technically "don't own the game" I hope you can help.

I think the steps in here will help you: https://itch.io/t/49527/how-to-update-the-game

If you've purchased the game, check out the "already bought" link in that guide.

- Have checked my junk, inbox, and trash and cant find the resent purchases email! Dose that mean I cant get back the email?
