Insert disk problem for Island Paradise and Univeristy?!?!?! [SOLVED]

So I have installed from Games4theworld Ambitions, Late night, Master suite stuff, Showtime, and Supernatural. I have bought the sims original game, Generations, and Seasons. Your downloads are the best but I have downloaded both University and Island Paradise and when I went to go play it it said please insert Island Paradise disk. I spent all night looking for a solution I got the ultimate fix and installed and the cracks to but it just wont work. The I uninstalled Island Paradise and then tried to play but it said again please insert university disk. Then I uninstalled University and played it again and it did work it worked perfectly. I can't seem to install the other two. They are the ones i really want. Help :/

Did did all of that many times does not work I think I should just give up on it.

I don't know what I did but I uninstalled and put them in and the cd mod and removed all the fixes and put the other ones in and it finally worked :]
