My Hampton Ceiling fan remote has stopped working correctly. I first changed the battery, thinking that it was not powerful enough to transmit the signal correctly. Didn't change it. The lights are on when the switch on the wall is on, but I can't turn them off with the remote. I tried checking the little switches in the remote to see if they had been bumped and changed. Any tricks or suggestions about the lights?

I forgot to add that the fan works just fine with the remote.
