Where does BallisticNG store it's files?
You may want to open the compatibility mode settings for the different executables, and enable "Run as Administrator"; you should also try un-setting the game's folders and files as Read Only (a common problem on newer Windows versions)

Since it's the Steam version, I am guessing the game will store it's internal files under "C:\Program Files\steam\steamapps\common"
But it might also store settings under "My Documents"
