How can I find out why my world won't export? Solved!

@ts1depot
Thanks for your suggestions. I was able to get it to work again. I had to move my Sims 3 folder and let the game generate a new one. I had to reinstall all of my Store content and my library, but it worked. I don't know why, but that worked. I'm glad you were able to help. This would have taken much longer to figure out on my own
