The computer I am using to connect has Pro installed (Florida). The computer I am connecting to has Free installed (Ohio). This has worked great for a long time. Today I started my Florida computer and attempted to connect to my Ohio computer. I was asked for my password (Custom PW) and the system took it, but when the connection was established, I got a black box in the middle of my Florida monitor. I can't get it to do anything beyond that point. Both sides are up to date on updates. The Florida computer only indicates 1 monitor on the Ohio computer, but there are 2 both of which were always found in the past.

What am I missing?
