help at level 5!!!!

Hi.

In medium (with the save I've downloaded), I killed Zimmerman without problems the first time I tried, but in Hard I can't kill him. One time, I Almost killed him (one shot left and he would die) but this time disappointed me. I tried two times again and I lost. It's really boring to kill the scorpion everytime I want to fight against Zimmerman. I've tried a trainer, it didn't work. I've tried cheat codes, in hard they don't work. It's the first time I wanted to cheat...

So, I only have one solution. Does someone have a save in hard just after this scene ? I don't want to restart the game in medium, I want to finish the game before restarting it. Thanks
