Cant take pictures-accidently deleted files!

hi

i was deleting images on my pc using a data cable and my samsung f110 micoach phone.

i think i must have deleted a software file because the phone refuses to take pictures now. when i try to take pic the screen goes blank and the icon of a camera comes on. this then changes to a snowy fuzz and then back again to the blank screen with icon.


does anyone know how to solve this? Thanks
