HP probook 4540s FingerPrint problem

i have windows 8 x64 and i installed fingerprint sensor driver and protect tools for my opertating system and increase my windows security using administrative console but fingerprint sesnor doesn't work .. i found something that the icon of validity sensor in control panel didn't appear on win 7 and win 8 now and i don't know why .. when i touch the sensor it gives no feed back .. by the way when i right click my computer , properties and device manager i see that the sensor is verified
