PC Game still not working HELP!?

My Virtual Villagers 3 down loaded game will not run.

It worked fine for 5 days now when I try to open the game it says

the drmactivator application has stopped working there is a problem and windows will alert me if there is a answer.

How do I fix this? I have tried restarting, re downloading, making sure all other running programs are stopped. Any help would be appreciated. PC Game still not working HELP!?
Others have had this problem and it was due to the DEP (Data execution prevention) being turned on for all applications and not just the windows ones. You can try the steps below to see if it works for you.

DEP: (Data Execution Prevention)

If you are receiving the DRM activator error message do the following to correct the issue.

1 - Left click on Start

2.- Right click on Computer

3 - Left click on Properties

4 - Left click on Advanced System Settings

5 - Under Performance click on Settings

6 - Left click on Data Performance Settings

7 - Click on TURN ON DEP FOR ESSENTIAL WINDOWS PROGRAMS AND SETTINGS ONLY.

8 - Click on Apply and then OK.
