All settings reset at default

I would add to the above that you can just backup your entire “settings_XYZ” folder into a zip or 7z or other compressed archive and should your settings reset, you can just copy that folder back into the C:\Users\XXXXX\AppData\Local\CCP\EVE\c_program_files_(x86)_eve_LOGINNAME_sharedcache_tq_tranquility (or whatever your folder is called) folder to restore your settings. Just remember to do this regularly.
