Save game error

An error in The Sims 3 preventing you to save the game.

Note

 * If you have the Error just go to: Edit town and use the Just continue option. Then change something and you can save again. (Confirmed by at least one person- works for me** Note that I didn't have to change anything in town mode, just save BEFORE 'returning to game')
 * Failing that, minimise the game window with your current game (the one you want to save) still running and go to your Sims 3 savegame folder (\Documents\Electronic Arts\The Sims 3\Saves by default on Vista). Delete any .bad files (these are the 'failed' saves), delete or rename the .sims3 and .backup files for the current game and then return to the game window and save.
 * Restart the game or the computer
