Everything on the gallery is corrupt

I have tried everything from removing all CC, resetting cache, repairing the game, to completely deleting and uninstalling the game, then reinstalling, however my gallery remains corrupt.
Every time I open the gallery, what is meant to be photos comes up as red crosses, and if I try to click on something, it alerts me that the lot/room/household is corrupt and asks if I would like to delete (which I can't because the build doesn't belong to me).
