1. If I don't answer to you, check your privacy settings or just dm me in discord.
2. Always log in when you buy a modpack. You will unlock its page. Later you can revisit this page to download new updates for the mode. Same applies to hipolink.
3. If you have problems with your bank cards, try to use virtual cards of other banks.
Virtual cards known to work:
PayPal virtual card
Privacy.com card
If you know any other examples, pls let me know <3
