Map Preview Images Not Loading

For some reason, when viewing my maps from the Page Toolbar, every one I have has changed to look like this: I've tried deleting and reuploading the images on the map layer and tried creating a copy of each page, but it still shows up with the same thing. Is there any way to fix or reset these images?

Hi Just_a_Stoat! The images are generated by the largest (size-wise) file on that page, regardless of layer. Did you delete an art file from your library but not delete it from the page? It shouldn't make any difference, but times change. If you can't find a placed broken file to delete, try copying the page, but only copy select layers. You might be able to determine which layer the broken image is being generated from. In which case, you could copy everything but that layer in a page copy, and use regular copy/paste to move the other things over.
