Re: Problems adding CC to Sims 2
@Simmy86 Please let me know which packs do you have for The Sims 2, or if you just have the base game. If a piece of Mod or CC that you want requires a pack, it will not work if you're missing that pack.
Yes, to install Mods/CC for The Sims 2, all you have to do is create a Downloads folder in Documents\EA Games\The Sims 2\. Mods/CC that come as .package files go there, unless the creator has special instructions to install them. If you have .Sims2Pack files, you can install them using The Sims 2 Package Installer, which should automatically launch when you open such a file.
As for the error you encountered after using Graphics Rules Maker; that program has a bug where, if you do not force texture memory, the game throws a DirectX 9.0c error, which I believe happened in your case. Sometimes it also happens if you try to launch the game in fullscreen for the first time, or if you have both integrated and dedicated graphics and the game automatically picks integrated.
Graphics Rules Maker is extremely useful when playing on modern hardware, but that is a bug that hasn't been fixed in the version available on the developer's site.
