It is not possible to download the Assets required !! 
if this is what you are looking for...
1. click the cloud icon to open the assets menu
2. scroll down to find the file you seek...
if not what you seek you will perhaps need to define what you are in search of
hope this helps
They seem to download ok for me also.
Once you click the link for each file they will download to your downloads folder on your computer. If this is not the case try doing a search for the file name on your computer, the default file location may have changed. Once located create a new folder, (I have a folder called CGC_source_files), and move or extract them into this folder so you can easily locate them later.
Have a cookie and try again.
