Something weird - I downloaded the .exe, installed it, and started the launcher. All in about 10 minutes. Total installation is 55 MB. There does not seem to be an option to download the actual game, and I get a "you are logged in from a region that we do not allow" error when I try. Any ideas?
I used the download link sent in the e-mail from SWTOR.
Edit: Installation did check available disk space, asked for 20G and some change.
Yeah I had the same thing happen. Filled out my security questions, plopped in my answers, and away it went. Security answers seem to be case sensitive by the way.
