WMM2: Some of my transitions/effects are now missing?

I had some really cool transitions/effects like a
newspaper layout that I would use for an effect and a New
layout that would make it look like I was doing a New
broadcast. But now they are gone and I don't know where
I got them from in the first place. Has anyone seen
theses or know where I can get some more cool
Transitions/effects? I already have the MS Media pack
and Fun pack.

Thx.Doug................
