All the trainer that I have used to this game don't crash for me. If you have a problem with money try to use this method : * Chose a buildind or one unit BUT don't place it on the battlefield (It's just to see the money down). * Activate the option to give money. * Then you can choose between place the building (or unit) on the battlefield or cancel this action.
After this your quantity of money increases in a gigantic way.
