I started as a .pdn and thought I converted it to a png, though, I might have done so without flattening all the layers so it can't open.

Is that my problem? How can I convert this back? I really need this

Try changing the file extension from .png to .pdn.

You may have saved a PDN file with the .png file extension.

1.  Open paint.net and check your File > Open Recent.

 

2.  You may have saved it to another folder, so check folders that you may have been working on at the time.

@PaintZMake sure you’re using the latest version of Paint.NET, which is 4.3.11. Your error log states you’re using 4.2.10, which is very old.
