this may not help but i have heard that if you use the numenor mod the units may be invisibel, so thet i say is it can be a mod problem or (just a thougt) the virus scanner thinks it is a virus so it stops (this would be more likely to be this if the all of the game stops but when it dont i dont know). try to not to use the trainer if it dosent work then you have a reall problem. you may not have the right version of the game. or just try to reinstall the game as a last way to try and fix it ( not garantied to help it work).
