run the client without data.pak?

Ok go to \bin folder and make a new text file.
Edit it and stick this in it:
Save it as launcher.bat
Then run the launcher.bat
Once game starts you can close the cmd window that pops up with launcher.bat :P

i did that any when i try to launch it using the launcher.bat, my screen goes black and then the launcher.bat is no longer there. this is when i've changed my shadow.txt's PackIO to 0.

my screen goes black also

is there anything else i can do to get my skills to work?
