Can anyone help me...I am unable to download this, part 3 has been the worst. My internet connection is generally good, I live in a city, what is the problem? I am on my third day of trying.
I'm guessing you are not using the GOG downloader, since it should download the files even if your internet connection drops out. The GOG downloader can resume from interruptions with no problems. However, it is only available for Windows and Mac at the moment. You need to download and install the downloader on your computer. Then on the same page you download your games, you should see an option to use the GOG downloader. Make sure the option to use the GOG downloader is set to "ON".

If you are using Linux, a member of the GOG forum has created a GOG downloader for Linux: http://www.gog.com/forum/general/lgogdownloader_gogdownloader_for_linux/page1
You can also use the DownThemAll extension for the Firefox web browser: https://addons.mozilla.org/en-US/firefox/addon/downthemall/?src=search
Since I'm on Windows, I prefer to use the GOG downloader. But for everything else, I use DownThemAll, because you can pause and resume downloads, so network drop out is not a problem.
