A "trainer" is a third-party program that is designed to alter memory locations 
of running programs (games). In order for a trainer to work, it must be running 
simultaneously with the game it was written for. It is best to first start the 
game and actually begin playing, then switch back to Windows (using Alt+Tab) 
and run the trainer. Select the desired options and switch back to the game. 
Do not CLOSE the trainer until you are finished playing the game. Since 
trainers are written to alter SPECIFIC memory locations, they usually only 
work with specific versions of the game. This is the most common problem 
when trainers seem to be "not working".
