that sounds a bit like an issue with permissions on the files or the file set.
Keep in mind that file sets themselves can also have permissions, as can the file manager itself at /index.php/dashboard/system/files/permissions. For the file manager the 'View Files' permission would also need to have guest permissions, and then the cache cleared.
If you can't work it out, I'm happy to take a look to see if I can spot something - if you are comfortable to do so you're welcome to send through a login to ryan@mesuva.com.au
