Most likely you had the 8.4 version installed before. If you are on Windows 7, 8, 8.1 or 10, try to delete the folder Flatcam located as you can see in the picture or at least the 2 files located in that folder. Replace 'mars' with your username. Then start again FlatCAM and adjust your default values in the Option TAB. Hopefully this will solve your issue. LE: To access that folder you need to uncheck the hidden items in Windows Explorer as some of the folders in the path are hidden. (//muut.com/u/flatcam/s1/:flatcam:pkPj:1.jpg.jpg)
