This is only a guess and I have not used the editor, so if all else fails.
do this at your own risk.
1. go to systems
2. click Advanced system settings
3. click the Advanced tab
4. click the settings tab in the performance visual effects, etc
5. click the Data Execution Prevention tab
6. Turn off the DEP
7. try the editor again
edit
let us know how you made out. I am on my second go round with Far Cry 2.
