Glam Hypnotizer/Seeing stars set :/

Hi.
Ive downloaded this and installed it yet for some reason it isnt showing in my game? It's on the launcher as saying it's installed but when I close the launcher and re-open it says it needs to be installed again, I even tried unistalling all my sims 3 packs and re-installing but still no luck. Any idea what's wrong?

Thanks. It seems to have worked with cc magic but now when I try and load up patterns in game its forever spinning on 'materializing materials' :s
