hi,
the patch you can download from the "stardustwars directors cut" site is for the director cut version only! it is not compatible with "stardustwars" wich is on a completely separet site. dont try to mix it together!
you only need to patch the dc version if you have an older version of dc .(so you don' t need to download the whole 800mb zip again.) if you download the full game you don't need to patch it.
