Instalation

Hello everyone.
I haven't use my Hog 4 PC lately, since everything got stopped.
Yesterday I tried to open it and it gave me a message that the app was not responding.
I looked for updates on the web page and reinstall it. It is still giving me the same message.
Recently I upgraded the virus protection on my PC as well.
Could this be the reason why it is not responding.
I checked the firewall buyt the app is not listed.
Anybody has any Idea of what can be happening?
