Bare with me! Bad english here...
This looks similar to vindictus when they patched the game to block modding, but modders made a file (.bat or cmd I dunno) that would move the moded files out of the game folder while the game checks for file changes, and immediately a after file check was done the cmd app would put the moded file back in the game folder.
I remember that you would have to mannually set a timer when the cmd had to put the moded files (it was different for everyone since this was slower for some and faster for others) back but that was not so hard
Now.... I noticed that after you press launch there is a file checker in the right corner of the screen and after that's done the game seems to have another one in full screen for about 7-9 seconds then the screen blinks for a half a second and then the game starts. I think that, that blink thing is where we need to cut the PAD00001.PAZ file out of that damn Paz(money hungry ass) folder!
