Help! I am taking pictures this weekend of some families that traveled from around the US, but i am not able to charge my flash battery. It turns red then green and never charges. I put it in the flash and it works for just a second and then turns off. I saw something about plugging it and replugging it and that did not help. Any ideas? I have not used it since Christmas, but it worked fine then. I will try anything!
