I am running the free version of Teamviewer. Prior to the most recent upgrade I had set the option to have a black screen on the remote workstation. After the most recent upgrade I am now unable to turn off black screen. I get a message that black screen toggling is not enabled in the free version. So this means I can never turn it off which means I can not access my remote workstation when I am home sitting in front of it. Do you have a recommendation how to fix that. Thanks a lot!
