Query: Please watch yourself for a unstable but expensive camera

I bought Olympus C765 at Apr. 28, 2004. At first, it was the great experience. Everything worked and I only use the camera for about several times since. Recently I found out the navigation bar and OK button is not working at all. In a word, I can not upload picture, erase picture, and view the pictures from one to the other. This is very expensive camera and I paid $419 for it. I never expect the camera broke so quickly. It is on the way to Olympus repair center now and I have to pay the shipping for it.
