I had the same issue and Trauen's suggestion to (SYSTEM RESTORE) worked perfectly! I would suggest that everyone do this if they are seeing issues! Good luck all!

My friend got the same issue when he installed the update and after system restore it worked. Hope this helps, Because I tried many other methods posted and very few of them worked.
