I would not know which protocol your contribution could have transgressed, nope, with it everything is okay!
I just wanted to point you to the absolutely worth reading topic, but unfortunately it is disregarded by many, at least in my opinion.
For users who want to use these brushes or even tune them themselves, this topic can offer a lot. But, as you must have read then, there are repeated questions about the broken link of the first version of this bundle, as well as other questions which users could have answered themselves by reading the topic.
But reading for yourself seems to overwhelm more and more users. My only point was to encourage you to read, nothing more.
