Game won't run - Sims 2 Castaway

[kinkinkijkin]

I used to have this game myself, and can confirm that it should work. Try the latest stable to see if it works, and, if it does, do the ever-so-slightly more-work-to-do thing that JMC47 said (sorry for that, by the way, it's just that trying the stable is always easier for people who don't keep an archive of a large amount of dev builds on their own computer).
