    Thank you! I was able to download Mozilla with this fix.
    I also have a message that my windows 7 is counterfeit. The download was from Microsoft & the windows 7 key was purchased on Ebay. What can I do? I have a windows 7 disk & key from an old desk top that I no longer own. Could I use that and start over clean?
