Hey Summer!
To get an update it’s mostly just sending us an e-mail with the e-mail you purchased the product + the product name, and after that we’ll resend the updated files.
However, on major updates(Such as, Performance boosts, Anti-exploit implementations, new features) we do send out the batch ourselves to all buyers.
On minor updates(Such as, a color change in the UMG, adjusting a typo in one of the achievements) we normally just announce these here and on twitter, but however for these you should request the update as these changes would override the changes you may or may not have already made.
However when we do update a product, your download link will be extended with 7 extra days of download time, so if you miss that time frame you can ask us and we’ll extend it again.
Hope this info helps!
