The Updates finished, and I've also updated my Graphics Drivers, and it's not helping. Now the error message only shows up sometimes (See the Spoiler on the first Post). When I open Task Manager and look in Processes, "paintdotnet.exe" shows up for around 5 seconds, then disappear and doesn't show up again.
Any and every bit of help is greatly Appreciated. I tried using different Art Programs today just in case I'm unable to get PDN to work again, and I found they're all too complex for me.
EDIT: There were a few more updates. I left my Computer on over night to Download and Install them. When I woke up this morning I tried to open Paint.NET again and now it works.
