Hi Riley,
tried it again with the Type Optimised option, but that worked too.
Quite a large Photoshop file 294 Mb, but 2,47 Gigabyte when opened.
When I open the file in Illustrator, I get some warnings about missing fonts, one of them is ESRIDefaultMarker.
That seems to be a font on a locked layer. Even when I unlock all layers, it cannot be replaced, because it's on a locked layer!
So that's something to investigate.
