I just found out about this problem as my game didn't start up, as earlier today it did. I started up the program using the TS3.exe file which bypasses the Sims3 launcher.
This TS3.exe file is located in tthe following folder:
(32-bit) c:\Program Files\Electronic Arts\The Sims3\Game\Bin
or c:\Program Files\Origin Games\The Sims3\Game\Bin
(64-bit) c:\Program Files (x86)\Electronic Arts\The Sims3\Game\Bin
or c:\Program Files(x86)\Origin Games\The Sims3\Game\Bin
Groetjes, Cheers, Gruessen,
