IPhoto is not coming up properly


When I attach my camera to download pictures or even just go into iphoto the Iphoto titles including all file, edit, help etc comes up at top of page but nothing else so can't download anything. I have recently moved countries and the computer was shipped but have downloaded once before this happened and it was fine then. I keep trying but nothing else comes up tried some of the titles at top of page but none get me anywhere. Please help want to download pictures have had trouble with memory cards in past and am worried if dont get them onto the computer might lose them!
