We have identified that a recent Windows update may interfere with the zAmp driver and prevent NeurOptimal® from running properly.

Until further notice, please do not install Windows updates on the computer you use for NeurOptimal® Sessions.

Our team is actively working on a solution and will share an update here as soon as one is available.

Thank you for your patience and understanding.
