I've used Paint.net a lot. After I finished working on something I shut off my computer, like normal. The next day I try to open it, but I can't. I uninstalled the program, and tried re-installing. It get this message: https://gyazo.com/4a65190df4b6dd357e77de04bbf87fe2 When it downloads it has a 'staging' folder with the installer inside. I recently upgraded to Windows 10, maybe thats the problem? Help if you can, and get back as soon as you can.
