Can't seem to load into a lot and error pops up

Hi guys,

Ive downloaded the most recent expansion pack, cats and dogs and i played it once and everything was fine. 
Next day the game loads to worlds and i edited some sims before selecting a lot to play and during the loading screen, it dims and then shows me an error! 
When downloading the cats and dogs, i didn't rename the game folder to game_ because i forgot to and once i did, the problem still persists. I've also tried downloading the endless loading screen update but still no luck.

I've attached a photo for you guys to see, the error reads: 
"The game failed to load. Error Code:
102:70c7f9a6:8998dd17. It is recommended that you relaunch the game."

please let me know if it was something i did wrong or the game itself, THANKS!!!

This error is currently being addressed by EA. Seems they messed something up really bad, and have yet to figure it out. I refer you to the official thread. It's long.

In essence, I suggest you only use a new game, and only "save as". If you overwrite your old saves, there is a good chance they may no longer be usable. It's not something you did wrong, it's a bug introduced with the expansion and/or the update.

Thanks for your reply, also i did some research and found a workaround the error.

On the start up menu screen you click load game and select a previous saved game and click recover and then just load that. It worked for me!
