after i tried the clean the lense, my camera stopped functioning. I can't see the image on the digital screen any more, and even if it looks like it's functioning, it doesn't take any photos. there is a hand picture on the lower middle of the right hand side of the digital screen. I'm not sure what I can do to fix it. Can you help me? what does the hand picture mean? I can still see the pictures Ive taken before i tried to clean the lense with a lense cleaning spray. so the digital screen is working for the previous photos.
