Windows Photo Gallery issue

Hi. I just got Vista with the Windows Photo Gallery and I am having
some issues with it and I was hoping someone could help. First, I can
not get it to email pictures to anyone. It does nothing when I try to
email. And then I just download video off of my camcorder and they
won't work. All I get is a picture of a hot air balloon. I need help
please. Any help would be great. Thank you in advance.
