You can download the patches for the EE without any problem. When you apply them, the system will first check if you have registered the copy online or not. That's pretty much the only time when you had to do it and it wasn't mandatory until that point since you could apply the previous patches just fine. I don't like intrusive DRM but I can accept a simple key registering online (without any apparent limit) — and it had the added bonus of removing the disc check for the game.
