Sims 3 will not recognize my expansion packs

[Chubbykitty101]

I have Sims 3(PC) Pets and Island Paradise and have used them for awhile. My younger sister was playing them and said the animals were laggy. I played later, but not with the expansion packs. The next day I went on, but it said that all households that used pack stuff had been saved with an expansion pack that was no longer recognized on the game. Help!!

if trying to play your game at the moment exit out of your game completely just in case in the launcher and launch your launcher again  is all your ep and sp ticked in the launcher ? due to the new manager way of using/not using a pack if unticked it will not load the pack and therefore can give you that message

It works now!!
