My sims 2 was running fine, until recently. I have not altered the game other then adding a couple expansion packs. I can't get the dialog box to pop up when I press Control, shift, and C. I used to be able to. I've tried to fix this problem by downloading patches and I even deleted and then re-installed all my sims 2 materials. What can I do? Is it a vista problem or sims 2?

it isn't fare that if you dont have the code because u lost the box that u can't play the game!!!!

well u can't

No I can still use the game. In game play I sometimes use cheatcodes. In oder to do this you must type the cheat into a dialog box.To get to the dialog you must hold down control, shift, and C. When I do the dialog box doesnt appear anymore. It used to but not anymore.
