I feel the same as de4more.
The pack is good, it's a pity you can't edit it, I have 2 questions about the pack:
1 - Is it possible to somehow get the password from the pack?
2 - This is no longer a question, but a problem. Well, the pack was working for me, I was playing with it, and suddenly in an instant the pack stopped working at all, minecraft does not see it at startup, and not only on my computer. How to fix it?
