@archo2132 Did you ever install the pack on another computer? If so, you may still be able to find the code on that computer. Here's how:
Windows: https://sims3.crinrict.com/en/2013/09/how-to-find-your-serial-number.html
macOS: https://bluebellflora.com/finding-your-serial-key-using-terminal/
If you ever registered the pack in Origin or on the old Sims 3 site ( www.thesims3.com or store.thesims3.com ), it would still be in the Origin account you used back then. In that case, all you'd need to do would be to login to the account and download the pack from your game library, provided you already have a base game registered as well.
Other than that, there may not be anything you can do. You could contact EA customer support and see if you can get someone to help, but it's more likely that they won't. So you might unfortunately be out of luck.
