The Sims 3 Showtime

I recently updated my game to the latest version (a little late, I know) and ever since then, my level 8 Singer sim has not been able to audition for gigs, do sing-a-grams, perform at her steady gigs or perform for tips. She still rides around in her limo, but she can't do anything that boosts her career level. At home, I can click on her, press "singer...", and press "perform song...", but that's it. How do I fix this problem?!
