Tuesday night my laptop did some updates. Now I can't get on. I can with the desktop, just not the laptop. I know it has something to do with the firewall. The region handshake comes up each time. I did get the firewall up, and put Singularity Viewer as allowed. But not sure about TCP, and UDP. I have it on the list two times. Should it be just one, or more than one. It is a Dell computer, and it is Windows 10.
