Simulation and Firewalls
Depending upon your computer's operating system and/or the internet security programs you may be using, the Light-O-Rama Visualizer may not be able to communicate with the Sequence Editor or Show Player, due to being blocked by your firewall. In this case, you may need to take steps to tell your firewall to allow the Visualizer to communicate:
If you are using the Windows Firewall that is included in Windows from Windows Vista onwards, allowing the Visualizer to communicate is easy. The first time that you place the Visualizer into Simulation mode, the Windows Firewall will prompt you, stating that "Windows Firewall has blocked some features of this program". From that dialog, simply press the "Unblock" button. Depending upon the settings of your system, you may then be prompted again, with "Windows needs your permission to continue". If so, select "Continue".
If at any point you accidentally told Windows Firewall to keep blocking the Visualizer, you can change that by:
1.Pressing the Windows Start button
2.Typing "firewall" into the search box
3.Clicking on the "Windows Firewall" entry (note: not the "Windows Firewall with Advanced Security Options" entry)
4.Clicking "Allow a program through Windows Firewall" (on the left)
5.Select "Continue" if prompted
6.On the "Exceptions" tab, scroll through the list of programs until you find LORVisualizer
7.Place a check mark in front of LORVisualizer, and click OK
8.Restart the Visualizer
