System Error (by 3 users)

My Coolpix 3200 was working all ok until I unfortunately tried to help a friend to recover his SD memory card. I put the faulty SD memory card in the camera and tried to format it. As the camera wouldn't recognize the card, I tried playing with the card in and out from the camera. After doing this, I got "system error" on the LCD. Turning the camera on and off, taking the batteries in and out, putting another formated SD card -
Nothing brought my camera to work again. My I know why did this happen? Is there a way to fix it by myself? could I try to make a firmware upgrade to solve the probem? Please help..... Dany dsadan@bgu.ac.il
