Cannot download USB-SD Creator DMG file

Hi
Just tried to download the DMG USB-SD Creator file but it says source is not available.
snippet below

'Users/xxxx/Downloads/VuJwqyqf.dmg.part could not be saved, because the source file could not be read.

Try again later, or contact the server administrator.'

Done. Used browser other than Firefox. Guessing possible java permissions issue.....
