If DRE detects Le Mans Ultimate (LMU) as running but does not connect or receive session data, do the following:
- Start LMU
- Open General Settings in LMU
- Scroll to the bottom
- Make sure Enable Plugins is set to ON.
- Fully restart LMU and join the track.
DRE uses a LMU plugin to receive live session data, so it cannot connect while LMU plugins are disabled.
