I guess I'll have to patch up now that I think about it - the simport requires you to have the latest patch installed, doesn't it?
Seabody is correct. This is not a usual "launcher", or incremental, patch, it's the manual cumulative "super-patcher" which includes all patches ever released and is only necessary if you don't know your regional code or if there are some issues existing. This time, however, it's the only choice, or at least the only "official" one. You can still use a smaller patch file to patch up from 1.31 to 1.33 but there isn't one for 1.32 to 1.33.
The reason EA is doing this is because there have been numerous problems with the last two super-patches and this one is *supposed* to fix them all in one patch. However, it only adds to the bunch. There's one long guide
here at MTS to (hopefully) fixing any and all bugs players have occurred due to installing these three patches. Currently the only bug I noticed in my game is that my Collections folder is empty and that is to do with one of the super-patches. I can live with it though.
Edit: BellaClo beat me to it.
