Hmm strange, I can't download anything from that box website. :/
When I click "Download" nothing happens.
Extremely strange. Strange indeed.
These links have been around for years and I merely 'updated' the content and used the existing links. However I have noticed that newer Box.Com shared links are 2-3X longer than before.
As such, I deleted all links to all contents, resources, engine and language packs; and then re-uploaded all content and generated brand new links.
Thank you.
That helped.
Now I can download the files without problems. :)
