I need advice on updating SOLVED

If you are worried, and obviously you are, hence your post, make a back-up of your saves file. I make a copy of mine and place it on my desktop. Then, after you've updated, if your game goes wonky, when played vanilla, you have a copy of your saves. So far, so good in my game. I'm already playing a risky save, as I kept the Road to Fame mod in my Mods folder, even after I returned the Mods folder to my game. I only created this save to be able to try out the My Wedding Stories pack, so if it breaks I won't cry. I simply won't touch my on-going save with the same Sims, until RTF has been updated. If I lose thatsave, I will cry.
