Cntrl SHIFT C not working

Hi all,
I’ve recently opened back up The Sims after a while of playing, making sure it’s updated too. And for some reason I cannot open the cheat window (which would normally be able to be accessed with the code of “Ctrl. SHIFT. C.”. However, it’s not working. 

I know for a fact my keys (on my keyboard) aren't the problem. Just wondering if it would be a recent patch issue?

I’d really appreciate the help. 

Thanks, and hope someone can help me soon- before I start going insane. Hahaha!
