I havent used this program in several years so I dont know if its me, my PC(resolution, vista) either way I cant seem to find a solution. I am following the "writing a logo with light" tutorial and I have done it and when I set the viewport to "draft" i get a perfect working version now when I set it to preview I get a white screen for the first 30frames and then frame 32 the particles appear without the background heres a few snapshots.

I've tried rendering our in colour+alpha and colour as a targa sequence and all I get is what the first screenshot is giving me nothing for the first 30frames and then black/white particles with no background footage.
my resolution is: 1680x1050 and i have a highspec machine so this shouldnt effect anything :( anyhelp much appriciated and thanks,
