I have a 378Pro with lost connectivity

I have a 378Pro that has a red light in the left corner. It turns blue when you  hover the pen over it but it is not interactive?


  • Hi crheil,

    Thank you for posting to the Support Community. 

    The red LED in the top left corner indicates a connection issue. Please make sure that the USB cable is connected to your computer and into the board. If a wall-box or connection panel is in use, try bypassing it and plugging directly into the board. 

    Also, you may want to check to make sure that you have the latest driver version on your computer, the latest is 5.16.7 and can be downloaded here, http://support.prometheanworld.com/product/activdriver
