Hello @Senlina, and welcome to the forum!
I had to move your topic out of the Brushes and Bundles resources category, because that is, if you had read the categories escription you would new it, only for posting resources for other users to download, therefore I moved it into our support area.
Additionally I changed your headline, because it is not conform with our rules, rules you granted to obey with confirming your registration to the forum. A headline has to describe your issue, if possible with only a few words.
Now to your issue:
You forgot to name your OS and its version, put it in your answer.
The same is true for your version of Krita, which version of Krita do you use?
From where have you got your version of Krita?
Can you please try the tips I gave another user in this topic, and please report back if there is something you don’t understand or if you are stuck. In either case, please describe your issue in a way that someone who doesn’t see what you see and doesn’t know about your issue what you know in a way that we can understand. A sentence like "I’ve tried everything only says you have done many things and are stuck somewhere, we need to know what exactly you did and where you are stuck.
Thank you very much!
