Selenium WebDriver Dynamic acess button Error

I´m trying to do a full download of the pdfs from my University Page but i´m stuck in a part where a dynamic JavaScript part appears.

I can login, acess the courses page and then after click the correct course a "page" appears where I need to click at least two "buttons" to acess the files.

I keep getting error trying to do the same approach I have done to login and acess the course page. How can i solve it?
