Hello! I have a problem. There is a picture that I'm working on at home, saved with Paint.NET 4.0.9, and I can't open it at work, where I am limited to a portable 3.36 (.NET 4.0 is installed, but any portable Paint.NET 4.x.x doesn't work). When I try to open the picture, I get an unspecified error. Any way to save or alter the file so I can work on it at work, too? Or a reliable portable 4.0.x?
