Realistic 1 trouble *SPOILER TO BE REMOVED*

I found the right file - administrator password = password:60c3309544*d16

status:administrator

AD: ******* and I know that this AD replaces the one I currently have. I seem to be making an absolute newb error somewhere though - I replace my current A****D with this new one (I use Opera which has a built in tool for doing this), save, exit, refresh page, and it replaces my edited ****** back to the original! I've tried using javascript code… I know Im missing something, and it's probably really nooby but for the life of me I dont know what , and I have checked google already, trouble is I dont really know what Im looking for…. What am I doing wrong? Help much appreciated :)

I think Im using the right javascript injection… ******:v**d(AD=here I put the numbers); Is that not right?

Sorry for double post, that was the wrong JS, but still it wont work. :vd(dt.c="A****=thenumbersgohere);
