I just bought CC 2D v. 1.70. I work with the standalone version on Windows 10 Home. My problem is that the PNG Export does not work correctly. When I click on Export for the first time, all looks ok and I can save the character as PNG. But if I choose an option (Portrait, Full Body etc.), the picture itself disappears from the preview and I can only export the background, either transparent or colored. It stays this way if I try to export later w/o restarting CC.
