photos and videos black after xbmc uninstall

I removed xbmc off my iphone 4 ios 4.13 and after all my videos and pictures are black. I can see the thumbnails, but when I pull up the full size pictures and videos they are black. I can here the sound just a black picture. This is also the same for downloaded music videos. So I reinstalled xmbc and now I can see or watch the videos but the pictures are still black. Any help would be appreciated
