Forum:I just bought Dragon Valley and it wont work

so i have Supernatural, but my sister just took it with her to college. okay, so be it. i did a little research and since it was the most up-to-date version of the game that i had, i couldn't play the game without the disk. so i just purchased a new one, Dragon Valley, and installed it minutes ago. it still says i need the Supernatural disk. i'm a little frustrated and confused, anyone care to help me out? <3

-Okay so you'll have to wait until your sister gets out of college. You need to either wait until your sister gets out of college or buy another Supernatural disc. Though I'm not sure if you'll lose your progress. But if losing your progress happens a way to solve it is logging in into your sims account. But if it won't let you reinstall your discs and patch it and you should be able to log in and get your progress back. If you don't have a sims account you'll have to wait until your sister gets out of college.
