Can't play sims unleashed expansion?

[Ctblue796]

so i install the original sims, then i install the hot date expansion pack, then i install the unleased expansion pack. Now every time i open the sims i get this update message saying something like this: The updater has found that you have installed another expansion after this, so this installer will have to fix that. Every time i click ok, it asks me to uninstall unleashed. I did it the first time and it uninstalled my whole sims collection, so i had to install the sims again. My question why am i getting this message when i didn't install any other expansion pack after sims unleashed?
