What does that mean at Netflix

You have downloaded too many things, now you have reached the limit and can no longer download anything.

Believe that you can only download the film often and that the limit has been reached

Exactly what it says there. You downloaded too many episodes. Try to delete some that you've already seen.

But other series I can only download Pretty Little Liars

It actually stands there.
It means that you can't download movies / series because you have already downloaded too many.
Maybe you could delete a pair again, maybe it will work again.

According to the error code:

"This message means that you have reached the maximum number of downloads for a particular series or movie.

For some series and films, downloads are limited to a certain number per year and account. If you want to watch the song before the end of the year, you'll need to connect to the internet and stream the song. Otherwise, please select a different title to download. "

I already have, I can only download the others

Then you have to wait a year.
