It helps if you list what steps you have already taken to try to fix the issue when you ask for help.
When you downloaded it, did you try the same method every time, or did you try the other method?
That is, if you downloaded it through bittorrent, try downloading it through a direct link.
If nothing is working, you can try waiting for the mirrors to be updated and try to use the updater. But that isn't setup at this time, I don't believe.
