Off camera flash not working

I was doing headshots last week for a friend and couldn't get my off camera flash to work. I have a K-x and always use it in manual mode. The shutter speed was below 1/120 the whole time. I use Cactus V4s, and I know they were communicating with each other, because when I pressed the test button on the transmitter, the flash would go off. My flash is a LumoPro LP160. So I can only assume the camera wasn't telling the flash to go off. It's been probably almost a year since I've done off-camera flash. What am I missing?? Thank you so much for any/all help and advice. I'll check this thread frequently, so if you have any diagnostic questions for me, I'll hopefully be able to answer them right away.

Does the flash work on-camera?
Do you have a different flash to test with?
I have Cactus v5 not v4 so not sure about v4 but can you swap them back & forth? v5 are both transmitter and receiver depending on switch
Does the on-board flash fire under same conditions?
Is flash turned off in the flash settings?

So this is embarrassing...but in the course of trying to answer your questions, I replaced the batteries in my transceivers, and now everything works fine. I feel sheepish. But you did fix my problem, because I wouldn't have done that if you hadn't asked me those questions! Thanks!
