Anti-theft did not work properly in windows 10

[suvivar 0]

I have not had any problems with anti-theft function in windows 7. A few days ago, after I upgraded my OS to windows 10, I could not use the anti-theft function. 

Particularly, When I logged in into anti-theft account and pressed "optimization" to create a phantom account. The website said this step was done, but on my computer, no any phantom account was created. Additionally, when I try to "run a test" on the website, instead of taking pictures from webcam and desktop and delivering a notice, no actions was done and a spinning icon was showed next to the blurred button "run a test again".

I tried different solutions, such as: reinstalling ESET smart security or removing the laptop account on the website before adding it again, but nothing was changed. 

Could anyone help me to solve this issue?

Many thanks in advance,
