Umm, I went back into hypergraph and deleted all the Extrudes I did on the faces. And this time when I tried doing the boolen it DID work. YAAAAAAAAY! hehe Perhaps it WAS the open faces. Perhaps it wasnt. Because I tried another test doing the same extrudes on another cube and the same transforms, and the boolean Worked! /shrug. Have no clue what the REAL cause was. But now everything is back in Order. Whew! thanks again.
