Good point. After all, it wouldn't be The Sims 3 without something like the game running out of memory at a pretty inopportune moment, like when you're trying to save the game or moving in between whatever world your primary lot is and Oasis Landing/the University town/one of the World Adventures worlds.

@smartie_icecream If you're going to uninstall, do it manually, and make sure you remove all the hidden library files that might otherwise prevent the game from launching. Here's a guide:

Install the base game only, no packs, and run the Super Patch again. Then try launching the game. If you still get the unknown error, let me know. If you get the server error, ignore it.
