trouble with Rules.ini, ........ Options

[Ghost Stalker]

uhm.... so, I'm trying to edit Ghost Stalker, won't go in details, and I have done it, but... how the heck I get it in the game? I try to use XCC Mix editor, create Expand02.mix in the SUN folder, stuff rules.ini in, save and start the game. What am I doing wrong?

Heres the code I edited
