I downloaded 'The Sims 3' and I could play it just fine, but when I downladed 'The Sims 3 World Adventures' It continues to say 'Your Sims 3 base game is incompatable with the current Sims 3 expansion pack. Please update your game Via the game launcher' But the Game launcher just freezes and wont let me Play or Updat Or anything! IDK what to do. I tried to uninstall and Re-install many times, but nothing happend. It wont even let me re-install it or un-Install it! Help me!
