oh why oh wyh can't i patch
 

can someone shed some light on why i cannot apply a patch with trainers included using ppfomatic.
i'm using CDRWIN to create the .bin file for tomb raider 5 PAL engish version but the .ppf file seems to be the wrong size for patching...... or am a just being dumb?
this is the first game i have tryed to patch. i can back up the game no problem!!!
