Exporting 3ds max models to .MDX

i'm using 3ds Max 9 to create my models, so
I have imported a m2 file(WoW) into 3ds, and when i run the Import/Export MDX v2 script to expor it to .MDX the script doesnt Run, is there another script to do it?

another thing

is there a BLP > TGA/BMP and TGA/BMP > BLP conversor to convert the blp images?
WC3 Image Extracotor II doesnt work in some BLP images
BLPConv.exe i dont know how to use it, if possible, explain my how it work

thanks

BLPConv has a readme that explains how to use it. (actually it's used like every other command line tool)

ok

but i cant export my models to .mdx
i'm using 3dsmax 8, the Warcraft art tools(blizzard) doesnt work
is there a MDX exporter to 3dsmax 8? if possible tell me where i can download it

thanks
