Expansions not showing up?

I installed the Base Game and the University expansion pack. There is a folder in my package contents named Sims 3 University Life but when I open the launcher the icon is grayed out. I tried playing the game and the expansion pack isn't even installed. I used the recent mac guide listed on the website

Can anyone help?

//EDIT

I accidentally put the wrong size for the Disk Image. I reinstalled it and now it works.

Anything else we can help you with?
