I have utilized Media Builder 3D Text, Flaming text, and Animation
Online to create animated text, how come once I download it to my own
PC and try to access it later or copy it onto my personal website, the
animation is lost - what did I do wrong? Or what can I do to keep the
animation?  Please help! Thanks!

Please describe how you are saving it or exporting it, where, and what
kind of file you are saving it as.

I've tried 2 ways - 1.) I just right click the text (from the original
site, i.e. flaming text, animation online, etc.) and click Save
As...and I usually just save it to My Documents under My Pictures. 
Then, I'll will go back to where I just saved it and sometimes, the
animation will still be there, but then it won't stay...a few hours
later, the animation is gone.  Other times, the animation isn't there
at all, just the text. 2.) I will right click the animated item and
click Copy, then I will go to my personal site which is under
groups.msn.com, and paste it directly onto my site.  The animation is
still there, however, a few hours later, the whole item will be gone
with just an empty box with a red x in it.

Any help you can give will be appreciated.  Thank you!
