I publish this post because some people have asked me that question and well, it is simple once the payment is made in the details of the order, there is the download link but if you have not downloaded it yet or want to download an update, this is the procedure:
1 log in with your username and password at b4xstore.xyz
2. Enter your user panel now go to the recent orders section at the bottom of your panel
4. click on view order
5. ready from here you can see the download link and you can download it whenever you need it.
