This could be due to you having installed older drivers for the Launchpad. Please ensure you have downloaded the latest drivers from our website:

Also, it is probably worth checking you have the latest version of Ableton Live installed:

Please also check that If you have multiple controllers when you remove the others the problem persists. If you have to use a hub, please ensure it is a powered hub like the Audiohub 2x4.
