The faults probably on your side. These files get downloaded 100.000's of times and most people who have issues with it have a malfunction on their side (of course you could be the exception).
First, get a decent browser like
Firefox. Install it and delete your temp internet files in case IE has left some mess from your previous download there.
Then,if that does not work, check to see if you have a good antivirus. If you don't then get
Avg, it's free. Personally I suggest to get
Zonealarm, it has a firewall, antivirus and anti spyware and you can get a free 30 day trial.
If that doesn't work then try cleaning your computer, I could explain how to clean your registry, take out malfunctioning programs and do more stuff by hand or I could link you to
Tune up utilities, another free trial version that you can fully use with no restrictions for 30 days.
Good luck :thumbup:
