Downloaded Panorama Studio 3.5, entered correct data for registration and was informed my entries were wrong even though I entered information as given to me.
If you are absolutely certain that every detail is correct, e.g., Upper Case or Lower Case letters, O and 0 (zero), you will need to email infoservice@magix.net and ask their help.
