i'm modding the CE conversion of b40 (renamon's)
I have recursively extracted all the tags from b40 using HEK+
then i tested recompiling the map again without making any changes to the tags using cmd to run tool
i typed this in

tool build-cache-file levels\b40\b40 

then this came out

Failed to load/create D3d

I tried reinstalling HEK, reextracting recursively the tags, but everytime i typed this in, it doesn't work.
help?
