KSE provides limited Xbox editing support. Namely, you can't add or remove things or do anything that would change the size of the game. This includes changing the characters' name -- you must use the same number of characters as the gave you have. 
  More details (and there are a number of details) regarding the steps required for Xbox savegame editing can be found in the kse-readme.txt that comes with KSE.
