UPDATED ULTIMATE FIX for any errors when trying to launch TS4: http://adf.ly/1j93F6
IF THE ULTIMATE FIX ISN'T WORKING THEN TRY ONE OR ALL OF THESE SOLUTIONS:
SOLUTION 1: After making sure that no anti-virus or firewall is interfering with the game, you should try applying the "Ultimate fix" from games4theworld. That may already be enough, but in case it isn't, go on with the next steps.
SOLUTION 2: Try deleting the file named GameVersion.txt, which is located in
C:\Users\(your username)\Documents\Electronic Arts\The Sims 4. Then try
starting the game again.
SOLUTION 3: Also, try deleting the file named Default.ini. The file is
located in C:\Program files(x86)\The Sims 4\Game\Bin. Then try starting
the game again.
