I lost my manual and well, you know the rest of the story. i need a new registration code but it has to be for the COLLECTION, it's different than regular University Life. & I know this question will get Flagged and deleted so e-mail me at please understand. it's NOT just the regular University Life. It's the Collection. & it doesn't matter if you already registered your code on the site. I just want to install it on my computer. please. I'm desperate.
