My PDN file I'm working on isn't opening and it provides this: I've tried searching for ways to fix but I've found nothing. However, for some reason another file was made, but instead of .pdn it's .pdn~RF118be85. What does that mean? Does it help in recovering the file? EDIT: Nevermind, I fixed it by changing the file's name to a simple .pdn and converting it to a png. the layers were lost, but luckily the image is saved
