Use Create-A-World and installed Generations and/or the latest patch?  You might find out your copy stopped working.  That’s okay, a new version of CAW – version 0.2.0.148 – can be downloaded on the official site that is compatible with the newest game.  I’ll be sure to uploaded this version to the site soon.  Thanks to SimFans for the tip!
