When trying to launch iRacing directly from the Game Center on the bottom right an Error could be shown like below, if so please follow the steps to solve it:
Make sure to download and install the latest version of Motion Core.
In Game Center, make sure the iRacing motion code is installed.
Right-click on the iRacing line in Game Center.
Click on Motion Panel settings:
Click on ''Enable Automatic Start with game'' button (left option).
Make sure that the enabler is currently running by checking its status on the hidden icons next to the windows clock.
Please proceed to launch the game directly from its desktop icon and NOT from the Game Center.
Enjoy iRacing with D-BOX!
