Ok, so the problem is you cannot complete the download?
From your description, it sounds like Gigabyte's servers are the problem...
I just went to try, and most of the regions are fine (Asia, CA, US) but the EU link gets stuck.
I'm assuming then, that you're using the EU link?
I don't believe there's going to be any difference in the software obtained via each link, they should just be regional servers -- and something is wrong with the EU.
Just use the download links from another region.
