Game Guardian Crashes (Dragon City)

[MIQ2001]

Okay, so it's taken me a week to find a on actual working hack program of anything for Dragon City. Then I found Game Guardian and optimized Parallel Space. It showed the game in my process. I knew how to enter values. When I entered the new values they showed up. Then if I used them the game crashed. Even if I didn't, the game crashed after 20 seconds. It would never save the changed info or amounts then. So. Is this program entirely useless, or is there a bigger problem? Is it the game? Is there any hope for hacking the game because I'm sick of having to spend real money on it. I love the game though. Someone just let me know if I'm exhausting my efforts for nothing please...
