hkxcmd won't work to exportkf so 3ds max can load animation files

[Alustrium]

Ok, so i got to step 8 using this guide http://wiki.tesnexus.com/index.php/Working_with_animations_in_Skyrim and the hkxcmd tool won't export the "skeleton.hkx" file. I did everything slowly step by step on that guide. I type in hkxcmd exportkf "skeleton.hkx" "animations" "anim-out" and it says it can't find the skeleton.hkx file, it says "skeleton file not found at skeleton.hkx I tried different tings to see if it would work, and nothing. and the only "skeleton.hkx" file is in "character assets" and i tried that, it it still won't work. all i get is that it can't find the file. I'm losing my patience with this. tried to upload a pic, but apparently it's too big, so hopefully someone knows how to deal with this, and I'm not completely SCREWED out of what i plan to do with 3ds max.
