I am having the exact same problem, but mine is the two files 'SmallAura' and 'LargeAura'. I can't find 'LargeAura' ANYWHERE. I tried using the search on my computer, it found nothing. I tried going to the Feral Hearts folder on Program Files, and on C Drive. Neither had a file called LargeAura or even LargeAura_0.
I use Windows 7 if that helps.
