Dell E5440 Backlit Keyboard-Pointstick Not working!!

I have tried searching everywhere and can't seem to find any solution to this problem.  Recently, I ordered a backlit keyboard for my Dell E5440 laptop. I installed it just fine and the backlight works, but the pointstick in the middle of the keyboard is not functioning.  I have installed Dell System Manager to control the backlit settings but I can't find anything about how to make the point stick work.  Does anyone know how I can fix this issue?  Thank you in advance.
