The shared BOX Link is in a widget down the right side of the page.
I have had a few bandwidth issues but hope to have these ironed out soon.
To stop automated linking, there is now a password required – ‘ validate ‘
For some unknown reason, individual downloads are still being problematic but you can download all shared files using the button at the top of the files page.
If the box is down, then you can try Mega if you using Chrome of Firefox as a browser. This is due to the download being completed through HTML5. Just click the big M below!!

trying to get the imm5 codec, clicking the link in Box does nothing
Working on it!
Box is being a pain in the ****! Hopefully Mega will help whilst I sort out all the sharing options in BOX!
Thanks very much, this really got me out of a hole
Glad it helped!
