Close the game and loader.
Restart Medal. If necessary, reinstall it using our Medal Overlay Setup guide.
Close other overlays that may interfere.
Open Task Manager with Ctrl + Shift + Esc and check CPU usage.
If CPU usage stays close to 100%, close unnecessary applications.
Repeat the launch process with the game in Borderless mode.
If the overlay remains unresponsive, contact Synthera Support. You do not need to uninstall unrelated applications as a first troubleshooting step.
