So here's the long story. I was drawing on Sketchbook Pro 7, saved it as a .tiff file while drawing. Then my computer crashed after something opened and stopped responding. I went back in, knowing I saved right before the crash, thanking my lucky stars. But! When I tried to open the .tiff file, seeing that the preview was not showing, a new window opened up saying, "This is not a valid image file, it's format or it's size is not supported, or you may not have read permission for it.".
It will not preview in any photo editor or gallery, and I can't open it on Sketchbook Pro. I can't really find anything, only similar things but with .jpg, and nothing they have listed helps.
I tried EaseUS Data Recovery Wizard and File Repair in hopes of getting it back to normal, and tried to restore previous versions through my File Explorer, but that version doesn't work either.
File Repair states that: "Your file is empty. No data in it and nothing to repair."
So, I guess my question is: Will I ever be able to get it back? And how?
