My devices wont sync

Hi guys,

I need your help desperately.

When I connect devices such as Iriver Clix, flash memory, my phone, they
show up in My computer but not in the sync list /header in windows media
player. They also do not show in sync center. What is also unusual, is that
window media player flashes a quick "iriver clix detected" when I connect it,
but then it dosnt show up in the sync header.
I have reinstalled windows vista and still have this problem.
