Welcome to Windows 8.1. Nothing worked right after updating...not my webcam, not my encryption...have fun uninstalling and reinstalling all your drivers and generally pulling out your hair! I wish I had better advice but that's what finally fixed most of my problems.
Let this be a warning to everyone else to not upgrade unless you have to!
For everyone, I do hope that W10 turns out to be far more sane than W8 (aka WAIT!). If so, then W8 can do down in hsitory as somewhere between Windows Me and Vista.
There is a reson that W8 is still banned in many enterprises, and corporations are still buying machines with W7 installed, evn if they pay to have them downgraded (aka right-graded).
