Re: Katy Perry Register code doesn't work..

Yes, it is highlighted. I have windows 8.

When you go to CAS or Buy/build mode there should be a filter in the right side. Do you see the KPST icon there ? If so, try to filter by that and see if stuff shows up then.

I only have stuff in build/buy mode. Nothing in CAS. Is that normal? No new hairstyles?
