I got Sims 3 but whenever I try to load in a town, it stops me at 99%. I let it stay there for 3 hours to see, still stuck. The thing is, I only got Sims 3 recently on this laptop and I have 0 mods, CC or save files since I haven't gotten to properly play the game. I have all the packs.
@mavzien Doe this happen no matter which world you try to load? Please try a few, restarting your computer in between, to see whether it helps.
If not, the issue may be the automatic placement of venues that come with expansion packs: this process happens whenever you load a new world and sometimes causes the game to hang or freeze. There's a mod by Bluegenjutsu on the Sims Asylum that prevents the lots' auto placement; you'd need to register (for free) to access it. The mod is called something like "No placement of community lots" and is safe and well-regarded.
If the mod doesn't help, please run a dxdiag and attach it to a post.
If you don't want to use a mod, I can try sending you a blank save to see whether it loads properly; that should at least distinguish between this issue and other.
