Hi
I've been running 4.8 pro and recently got the message that it was about to expire so I upgraded to 5.0.507. I followed the instructions & downloaded the newer version, got my new reg key in my email, clicked on the download to install and it shows files transferring & then it stops and nothing else happens. I checked & I'm still running 4.8, the newer version never installed and I'm still getting the message that my avast is about to expire in 13 days when I've already purchased the new key. My OS is Vista & my browser is FF.
Thanks for your help.
