Atom thinks my C++ files are HTML, can't change settings

Hi Atom! I love the editor, but after installing Anaconda, Python3, Jupyter notebook, and nbopen I Atom opens all files as HTML. I can’t access the top menu of Atom to change any settings. I can’t access Atom’s settings or menus.


When I select ‘Toggle Dev Tools’ in the drop-down menu under the lower ‘Atom’ the window goes blank. I can’t access Atom’s settings to fix it’s behavior. Any help will be appreciated!

And I have uninstalled & reinstalled, I have Windows 10.
