screenshotPath=.C:\ProgramFiles\Ubisoft\SilentHunt er3
That above is your screenshot path. IT IS STILL WRONG!
You have a fullstop (.) after the = Remove that!
You have a space in the word Hunter. Remove that.
Also I'm pretty sure the correct folder name is SilentHunterIII (not using 3). That is unless you changed it.
Slow down a little and recheck it.
