I have completed the entire game, only the faith's quest I have failed, 'cause I had "taken advantage of her". Is there any way to mess with the .txt file and change some things so that I may be able to complete her quesT?

PS: I have captured the ghost for about 20 times in the Evergreen University but I am still unable to see Faith's spawn ever since I have broken her trust.  I DO NOT want to delete my possessed data or my ghost's collection.
