AngelaIp I don't think the relationship broke because the Files are not restricted for Admins.
We only have on MAC policy that controls the visibility of Documents. Therefore, I don't understand why would Document be visible and the files are not.
Also, I can't look at the database directly because we are on Aras cloud; don't have access to the database.
It´s probably the best to ask Aras about this one.
One option you have is to directly view the "Document Files" ItemType (just add it to the TOC). Maybe you see something unusual. The direct view of the ItemType also allows you to check the permissions of the relationships. Maybe you find something useful, but it´s not guaranteed.
In addition check, if the physical File is still accessible by checking the File ItemType.
