Am I supposed to download the patch now or will I have to wait untill at 00:00 (or 02:00) to download the patch?
I've bought Skyrim on steam, but I dont have any real experiences with steam. Will I be able to automatic download the patch with steam or?

I am confused.. I just want to play a fully patched Skyrim at 00:00 on my PC

Steam automatically patches when a patch is available. If it isn't patching right now, there either is no patch or it already patched.

When it becomes available, it will patch automatically. Should be release day patch, but they are probably waiting for the rest of us to enter 11/11/11.

I downloaded the patch on Steam this morning. If you already have Skyrim preloaded and still logged into Steam just log off and log back on and it will update.
