Sims 3 Create-A-World (CAW) now works with Ambitions – redownload Thanks to all who left comments on the site letting me know that Create-A-World now works with Ambitions.* According to The Sims Team, all you need to do is uninstall the current version of CAW then redownload the program from the official Sims 3 site and install it again.* So what are you waiting for, give it a go to see if it fixes the problem!
