It is not downloading all the slides

[Darktotaled]

I've been trying to download a motherboard manual as the company and its website doesn't exist anymore and slideshare is the only one i've found.

https://www.slideshare.net/lucianopollrs/sm3330

this is supposed to be a 66 pages manual but slideshare downloader only downloads the first 6 pages.
Is it something i doing wrong?
