I have a problem trying to open an AE file I created (after effects error unknown parser error 14 (39 :: 0)) I found out that this is because of the files, in this case Photoshop files. So I guessed that the files were damaged, I open them in PS and they are indeed damaged, some strange lines apear on the images. But the weird thing is, when I open any of these images in the picture viewer application they seem to be ok, or in the previous image viewer, only in PS they seem corrupted, does this still mean that the files are damaged or is it a PS issue???
Likely the layered files are damaged but you can still see the flattened preview in a viewer program. If you can live without the layers, you could try importing/opening the file into a different program and re-saving it from there.
