I'm trying to display .ers tiles, but every time I try to pull them into the map and error message appear saying invalid raster dataset and they fail to display. I have the same files stored in another folder and these work fine. I tried to copy the working files in, to replace those which won't, however once transferred into the same folder, these won't work either. As far as I can tell the auxiliary files aren't corrupted so I have no idea what's causing it. There are also .tif files on the same folder which work fine.
Anyone experienced similar problems or know how to fix this?
