Not sure it's your issue, but I think you should uncomment your [keychip] thing and the value (based on your IP) should be subnet=192.168.1.0
Also I can't tell based on your current info, and I know you already tried, but please continue testing all on C: drive.
Is your start.bat, inject.exe and InitialD0_DX11_Nu.exe all in the same folder? (<game dir>\app\package)
Are you still making sure inject.exe is running as admin somehow? Either via an admin cmd window and running start.bat or inject.exe set to run as admin by itself and just starting start.bat normally?
