What is wrong？

I want to download some files.
I think that reached download limit.
I have a lot of books to share, if it's necessary points to acquire these privilege.

I haven't Chinese native language.
Now i become to see the links for files.

Yesterday i try to put some files, but i didn't succeed.

The problem remains！
I wil share some files. But it's difficult to uncover the files already in the forum
