my standard software like imovie, iphoto and the itunes store stops when i open them!

Hi,

Recently my software of my macbook pro stoped working.

I was trying to open iphoto to configure it with my new iphone.

But suddenly it closed the program automatticly, and this is the same with the other software like imovie, the itunes store (itunes itself works fine).

Does somebody have the same problem?

And how can i fix this?
