I have use the save editor with versions 1.29 to 1.34, without running into any problems.
Was the save you edited working properly before this? Did you make a new save, or let the editor backup the data.000 file? If so you can revert to the previous version, make sure it works, make a new save or copy of the folder, and re-try editing. Alternately, since you are just starting the game again, you could create a new character, save and re-edit.
Try just giving yourself spare skill points. Maybe if you are putting more points into a skill than you should have at that character level, the game is choking on that. When I tried this (v1.32), the save loaded fine, but the edited skills did not change.
