On my girlfriend's computer I was able to safely kill all the files but on mine no matter what I did my computer just would not let me delete them. I was really looking forward to playing but I'm afraid to re-install it after having to format to get my drive space back. Maybe someday a more trusted client than the Windows Store will release the US version though I doubt it and that sucks. I'm never trusting the Windows Store again.
This kind of where I’m at.
