I'm about to start crying right now. I am trying to reinstall Sims 3 on my new laptop, and all the expansions I own are registered to my dmel25 account on Origin EXCEPT Sims 3 Late Night, I don't know...
@dmel15 Sorry to hear about your dilemma. If worse comes to worse, you could wait for Late Night to go on sale. I wish there was more I could do to help you. I am no longer able to get the Pet Shop that came with the limited edition of Pet's to work, but at least I am able to get the pack to work.
