I've had no problems with it and I play Sunset Valley 2 all the time but I did re-name it Starlight Valley as my saved game the only time I get an Error Code is when I try to save the game when something major is going to happen like getting robbed. I love Sunset Valley 2 its my Fav world cause I still have room for the Supernatural stuff but I'll have to remove that stage that came with the LE of showtime oh well I can do without it cause I put in the big show and I added a few lots to the world also cause I have the AP school in it also. I also have it with the lots added that way its alot easier for me to place the lots but come Sept 4th I'll delete it and start all over again on the town to make it perfect. good luck with it. thank you md for this world I 100% LOVE it!!!!!
