4.0.0 Updater

[Deleted]

Okay, so I downloaded patch 4.0.0.
I'm now running the updater, it's at 29% and I have around 8gb left on my HDD.
I have a feeling that's not enough.
How much is needed to complete the updater?
I also know I need another gb or so for the 4.0.1 patch.

PS. I haven't deleted any previous patch data, so I was wondering if it would be more efficient to reinstall the game from scratch.

the patch is ~4.6gb
to complete that update you will need 18gb free on your drive (you get most of it back after it has completed)
you then have to download another 1.6gb patch after 4.0.1 is complete
then another 15mb patch

then you can play
