Okay, so krita crashed while I was using it, and once I try to open the picture back up, it displays an error message saying the media is not supported. I haven't saved it as jpeg, png, ect. Please help!

Do you mean it wont open the autosaved image from the crash, or an image that was saved before the crash? And what is the extension or file type of the file in question?

It is the auto-saved picture, and I haven't saved it as anything other than .kra.
