Hey, and welcome to Android Central!

Couldn't you just punch in your back up pin instead?

Unlock using the alternate means (pattern/password/pin) , go into settings and set up your fingerprint again..

Welcome to Android Central! Which phone? Is it telling you that it can't recognize your fingerprint? Or are you putting your finger on the sensor and nothing is happening at all?
