You get that error when you are attempting to install the grader after it is already installed in your account. You don't need to install it again - just once the first time. After that you just use it.
There are two YouTube movies on the grader page that show you exactly how to do the steps give to run the grader. There is a short one and a long one. Watch either or both to see exactly how to get to the place where you paste in that line of code.
