# Frequently Asked Questions

<details>

<summary>When I try to launch a simulator, it says “port address in use.” What should I do?</summary>

When RouteEffect creates a simulated video router, it needs to bind to a specific port on your device. Only one application can use a given port at a time. If you see this error, it usually means a simulator is already running on that port.

To resolve this:

1. Open the Dashboard in RouteEffect.
2. Tap Stop All Simulators to shut down any active simulators.
3. If the issue persists, force quit RouteEffect and relaunch the app.

This should free up the port so you can start the simulator again.

Note: The Blackmagic Design Videohub Controller app for macOS also makes use of this port. So, when creating your Simulator entries, you may want to choose a port other than 9990.

<summary>What features can I use if I don’t subscribe to RouteEffect?</summary>

You’ll still be able to create Video Router entries and simulators, but only the first one in each list will actually run. You can use the Button and Wheel Picker views to route sources to destinations.

The more advanced stuff—like Split View, List View, Crosspoint Matrix, and Virtual Outputs—requires a license. Same goes for Multiview, Presets, and automating with Shortcuts.

It’s a great way to try things out before unlocking the full power of the app.

<summary>Is there a lifetime version of RouteEffect? I only see subscription options.</summary>

Yep! A lifetime version is available as a separate app called RouteEffect Pro on the App Store. It’s a one-time purchase, with no subscription required.

The regular RouteEffect app (the free download) only supports subscriptions. RouteEffect Pro is designed for people who prefer to pay once, or whose devices are managed by an organization that blocks In-App Purchases.

The lifetime price reflects the ongoing development and maintenance of the app, so you’ll keep getting updates and new features. It will also be enabled for Family Sharing.
