I'm trying to install the starter edition and it keeps telling me a file is corrupted and I need to redownload it or it's failing to read a required file and that I need to close all my applications and try again. I've done both things. What should I do? I'm meeting all system reqs and I got the starter edition through my friends guest pass.

EDIT: I found the thread http://us.battle.net/d3/en/forum/topic/5007750811 and it should be fixing the corrupted file, however now my launcher is updating and it isn't working. Whats up now?

EDIT 2: it's downloading properly now. After getting the file mentioned in the linked thread above.
