Well, let me suggest a trick a tech taught me... Cut your computer on and off, on and off, on and off, on and off.... Spend about 30 minutes just cutting it on and off, keep doing it.

I thought the guy was crazy when he told me to do that but it made my computer reconize what the problem was and we were able to correct it... IF one of those times reloading, a window pops up that isn't suppose to be there...... that is your problem.. Mine turned out to be a fire wall that was preinstalled on the computer.

I have used this trick and solved a lot of problems... Most of the time another window didn't open but the thing worked right after doing it. It's worth a try..... Post back and let me know if it works for you.
