I have three track lamps that I put X-10 "socket rocket" lamp modules in to control the lights. I've had them for about 2 weeks and everything's been fine, but then I tried to turn them on today and nothing happened. So I took one of the X-10 module out and tried it in another lamp and it worked fine. Then I put it back into the lamp it was in before and it didn't work again.

Anybody ever had this happen? Anyone know what to do?
