My WD smartware has stop working

Hi guys…suddenly that quote was appearing on my screen and my passport was not working… i have read somewhere here to unistall it and then reinstall it but now it doesn’t give the opportunity to install it…i can not find it anywhere but the light on my passport is on… which indicates that is working. Furthermore its working on other pcs…what is the problem mates? Please Help…

What do you mean that it’s working on other pc’s?  Are you able to unlock it with your password on other pc’s?
