The file in TDATA doesn't take off the update, it stores controls and preference settings. It's important, but probably not causing your problem (if you forget to use it, every single button will enable/disable wireframe mode).
Also... can you talk in proper english? Just is a lot easier to read and helps us
take you seriously-er.
Several other things - the trainer menu should be inside Xored - make sure you have 'disable autoupdate' and 'developer's mode' selected to Enabled, and hit start. You don't change the trainer settings or go to its menu while you're playing Halo2.
If you use EvolutionX as your dashboard, make sure to go to system settings, and change TSR from Normal to None.
