here a little app to give you some points :)
the app makes a backup and does the rehash/resign for you.
This editor is for the profile.prf file only !to earn your Achievement and Unlocking all your Skills/Powers/Upgrades you have to load up a Level and it will Update your Stats with all the Skills and pop up both Achievements in a Legit Order.
Edit: Fixed editor (Writing isseu)
it should work now for every save (i hope)
