At the top inside of IE11, click on 'Tools', then 'Internet Options', and then the tab on the far right named 'advanced', and at the bottom, you will see RESET. (This will reset ALL IE11 settings to default. (and delete all cookies and clean up everything. It will warn you what its doing).

But this should fix it. (remember to set your security back to med-high or however you had it, if you had a custom setting.) same for cookie settings. (this reset also checks for messed up registry entries, and resets them.)

Good luck! and let me know if this works!
