Are you at a high enough character level to be able to learn the skills you gave yourself?
If you are not trying to get around level restrictions, it may work better to use the editor to give yourself free skill points, and then learn the skills as usual within the game.
At least with iZakaroN's SaveEditor, when you edit your experience points, the game will not update your level until the next time you get experience in-game. Try defeating an an opponent or completing a quest.
