I write for a number of production libraries and have trusted soundcloud, up until recently, to hold my tracks so that I can download from any location, and have clients do the same. For certain tracks that I have uploaded I am receiving 'This track was not found. Maybe it has been removed'. I can plan play the track, it has not been removed. I am now using Dropbox for all future links to clients as this is so untrustworthy.
Additionally, please don't set up the system to be so convoluted that you cannot make direct contact with someone easily. Rapidly going off Soundcloud.

By default tracks are not downloadable. You need to enable this when you upload it. You can also enable downloads now by going to the permissions page for your tracks.
There is more information available here: https://help.soundcloud.com/hc/en-us/articles/115003565708-Enabling-downloads-for-your-track
Please try that and let us know if there is a problem.
