"No game disc found"

Hi!
 So, i have a (legal) copy of the sims 3, and downloaded Late Night, Supernatural, and and Showtime from here. I followed all the instructions and replaced all the right files and such, but when I try to start the game it says to insert a copy of Supernatural to play and it wont let me load my game. Is there another step or something that isnt covered in the tutorial?
Any help would be greatly appreciated!

Hello,
If you do all the steps of this article correctly this error shouldn't pop up.
So if your game isn't updated to the latest version already then (re)-download and (re)-apply the Manual patch from here then applying the Ultimate Fix correctly is the next step:
(Re)-download the Ultimate Fix from here if you haven't got it recently.
Open the Ultimate Fix folder and go STRAIGHT to #Crack folder and copy the content of that folder and paste it in C:\Program Files (x86)\Electronic Arts\The Sims 3\Game\Bin.
Run your game to see if it works!
Good luck for now!
