Re: Error Code 13

Just setting up my first small business in a small business venue. Tried to save the lot, and got "Error message 13. Game didn't save." Last time this happened, they fixed it by returning to a much earlier save and I lost almost a RL year of progress. I just bought Enchanted By Nature, and now I can't play again until I can be sure I won't lose all my progress. I don't want this to be the third time I've lost a large amount of progress on Sims 4. I've got over 5,000 hours and almost no progress saved. Please, I need help.

I have a pristine clean install; no mods or CC. I also have ALL the EPs, GPs, Stuff Packs, Kits, and 
Event Content, plus other Maxis freebies.
