I saved my old artwork i made yesterday on an older patch of paint.net. I saved the file as a .pdn and installed the latest update to paint.net. I now cannot open the file on paint.net or any other image viewing software as they do not recognize the .pdn file format.
Here is the error details:
System.ArgumentException: Parameter is not valid.
