The Sims 3 - Flash Error

I recently got the Sims 3 and when I'm at the Game Launcher window, before I can click the play button, this Flash Error pops up. When I click Dismiss All/Continue, the game says I am running an unauthorized version and there will be limited features. Then the game quits. This only happens sometimes but is quite annoying.

The error that occurred was:

Error #2044: Unhandled IOErrorEvent:. text=Error #2036: Load Never Completed.

Can someone help me out here?
Do I need to reinstall the Flash plugin or Flash CS4?

Thanks!
