every time i download any biped tag from this site and try to import it in sapien it says " Error One Or More Of The Items You Selected Can't Be Added, Please Contact Your Nearest Bungie Representative" and when i check the debug.txt there is errors out the freaking ASS!!! ive never seen so many, it seems like its for every tag associated with the biped.

Make sure you put the biped in the correct location. Usually, there's this helpful text file titled readme, which tells you exactly where to put it. Of course, most of us ignore those helpful readmes, even though the title just screams to be read.

find the debug.txt in your HEK installation folder, open it up and paste the paragraph that corresponds to the time when you put in your erroneous biped in your post.

ok. make sure

actor_variant tag 'characters\halo2\HDoan\marine\Johnson\john_formal assault rifle is in that folder.
