launcher stuck on 75% ("almost finished copying files")

This relates to http://askubuntu.com/questions/297524/wubi-installer-stuck-on-75

When I am on the second part of installing wubi/Ubuntu on my computer (when it boots into Ubuntu) it always seems to freeze at 75%. I've attached the logs, and hope you can help me.
