Is anyone else getting the message (when opening up in Windows Excel): 'The file you are trying to open, .... , is in a different format than specified by the file extension. etc..' ? I don't get this when using Mac Excel (2011), but it seems to be an issue with Windows Excel (2010). Any workarounds?
