Sims 3 Pets No Disk

Yesterday I installed Sims 3 and Sims 3 Generations. Today I installed sims 3 pets, and I did all of the things it siad to do on the ultimate fixer. When I open sims 3 launcher its all fine until I try and play the game. It says that there is no sims 3 pets disk. Help?

It seems like you did not apply the fix correctly or in the correct directory, please post where you applied the Pets fix to and where you applied the #crack to after updatinh to latest, if you are unsure if you have the latest check this-
