Ca't watch phone files on Windows movie Maker

Hello,

I plugged in my USB from my Nokia 5800 EXPRESS phone to my laptop to watch/edit some of my videos on Windows movie maker. When I play these files it shows that they are playing but I don't have a visual. Can someone please help me.

They are movies of my son, u know first steps first time at the park and all that, so I wanna put everything together. Can someone please help me. Wat do you think is the problem?

Thanks

Sabrina
