My game is now installing from the disk instead of downloading it.

I suggest anyone still trying to download do that same if your download is still gonna take more than 10min.

I'm doing exactly that right now. Found it here on the forums.

10min? 5gb download would take me about 11 days straight so don't complain

I knew for some reason the disk wasn't just empty when it says there's no space left on it. It has 5.1GB on it but that doesn't fully account for the 6GB that is skyrim.

I didn't mean it that way. The download estimated time for me was 5 hours using the johanesberg (IS) server, giving about 3MBpsdownload of the game. That was more for those who may think that they are close to finishing the download.
