With Sims 4 out I know Sims 2 it OLD news, but it's my favorite up to date and I'm having problems. If anyone is familiar with Sims 2 Deluxe it contains both Sims 2 and Sims Nightlife. My problem is this. I lost the disk a long time ago. However I still have all my files saved from my EA folder to my computer. I have transferred it from two computers and it has worked fine with other expansion packs piled on top of it. I may not be able to run Sims 2 Deluxe without the actual disk, but I can play the game nonetheless with another disk of an expansion pack. However, now, when I try to play an expansion pack (Sims 2 Best of Business) it says I have to install Sims 2 again. Is there any way of getting around this without going through the trouble of buying Deluxe again?
