By paying $25, you get all the content. Everything is in the package description. In the .zip file in the link updates, you will find the next updates. An update was uploaded today!
I looked at the download page, and it tells me that the last update was 31 days ago. I don't know if it's a problem on my end or what, but I was just wondering. Thank you for getting back to me.
When purchasing the complete package, please ensure that you have a .zip file named “link updates,” which contains a link to a drive where the updates are uploaded.
