| I had this same thing happen: battery ran down, I took it out and brought it with me to the store so I was sure to buy the right kind.  Came back, put the new battery in: Nothing.
 As it turned out, I had simply put the new battery back in upside down!  The Plus side goes DOWN, into the plastic drawer (it seemed more natural to me the other way, so I put it in wrong).
 
 I also realized that if the unit ever failed for real, I was hosed, so I bought a second one.  Now I have a backup, one for a second camera, or one that I can carry with the light meter, leaving the other on the camera.  Not too bad.
 
 Hopefully, it is the battery thing.  If not, though, call customer service: you are well inside warranty, and Paul Buff Customer Service is the best in the industry.
