able72,
To get around the 8 character thing possibly change background to back as I've highlighted below;

::Changing Startup SPlashscreen

::Generating a new Splashscreen
cd %root%\MODS\SplashScreen\GUI\Screens
RANDFILE *.tga back.tga

::Fix the SplashScreen name
:: Due to 8 chars MS-DOS limit, the name is too short
move back.tga "%root%\MODS\SplashScreen\GUI\background.tga"

Don't know whether this would make Vista happy, don't have it myself to check

EDIT: got my son to check it on his comp (vista 32 bit OS) all worked ok for him, using background or back as file names.

Cheers
