I have a brand new PC with Windows 10 and freshly installed SF13, but I cannot save as MP3. It doesn't recognise the format. MP3 format is essential for my work (lots of elearning clients require this format) and I need to be able to convert to it in Batch Converter. What am I doing wrong? I have rebooted the PC many times and also reset "all preferences and cached data" from the file menu, but still, MP3 is not an option in either the Save As format list or in Batch Converter.
