Left Click Not Working

For some reason my left click is not responding in cubase 8. It has been working fine. Not sure what to do…any help?

Thanks

What os?

Is it not working just while using CB or when using other programs too?

A few suggestions:
Have you tried replugging it in. Maybe to a different usb (on windows os). Try restarting CB or reboot the computer. Try a different mouse. They can fail (mine did).
