Tutorial Projects :3D Game Kit" not downloading

Hello everyone, not sure if this is the place to post this, but I wanted to see if anyone else has experienced issues downloading the Tutorial Projects 3D Game Kit?

I hit the download button but the bar keeps filling up until it reaches the edge of the Unity Screen and then nothing happens. No Start option appears or option to re-download. If I hover over the line, the X appears for me to cancel, and THEN the option to download appears again, but I just end up having the same results as before. It doesn't download.

I hope this is the right place to report this issue, and if not, sorry in advance!
