Medion Tevion Digital Camera

[jacko22]

Gentlemen, it's my Tevion Digital Slimline Camera, it's made by Medion. Recently I took 4 pictures. They are in the camera but won't transfer to my computer as all of my other pictures did. Also when I look at the pictures (in the camera) it highlights the last one taken and I cannot get on to the other three. The Control button (zoom in) doesn't seem to be working nor does the Menu button. Can you suggest what I can do, if anything, to overcome these problems or is it a case of looking for a new camera ? Many thanks in advance, Jack Simpson
