Hello, im user of Acer Aspire ES1-331. I have been using it from February 2016 with Windows 8.1
For a long time Acer Quick Access and Acer Bluelight Shield were working properly but some days ago something happened and: option of sharing WiFi disappeared (it was under "Rozruch do pulpitu") from AQA and it became impossible to turn on ABS. Earlier when i turned it on or off it happened immediately. Now some dots are going around for a few seconds and i get that:

It means : "You cant control that device" . the same happens when i change intensity of ABS - nothing changes however it can write that it changed. On the screen "high" level is turned on but you see that it is a lie. I am using it on Admin accoutn of course.
I reinstalled Acer Quick Access but nothing changed and i cant use Acer Bluelight Shield.
Rest of options of Acer Quick Acces works (Wifi and Bluetooth).
Thanks for reading!
