I bought my Nikon D200 this morning and when i came home i putted my battery in the camera, after i loaded the battery offcorse! When i putted the battery in it and my memorycard i heared a beep as asign that the battery was in the camera, but when i putted it on it didn't give any sign of life, even if i reloaded it again and again... I tried a lot but nothing worked, HELP!
