try inserting it with block tool. if you al ready did, try seing if the hex is right or something
Ew. No need.
I've had this problem before too Immortality. Close LM, close BTSD, and then reopen BTSD. Reopen your rom. Then, go to "reinsert all blocks." I think it's in the second of the top drop-down menus, but I don't know. After it's done it's thing, press save and then play your rom, it should work after that.
