Once you have opened and made the setup right, you can open the save game... You go to the Affect table by scrolling the top right arrows until it comes up, you click it when you see the Affects and it activates, you just have to remove the negative affect you gain from the kit by selecting it and pushing the Remove button(the affects name starts with 0x00BD), then just you need exit as is gives you the save selection, you save and you are done... you load up the save and play from there. You should also remove the "Experience" Affect as it makes you to have the percent number on from the total, it should be 85(%) on Param 1, so remove it.
