Most note that other browsers work in spite of the error.
My OS is Windows XP home
A while ago I downloaded Ashampoo firewall software from Download.com
as a backup,which has been sat in my documents folder. Just recently I
decided to install it on my PC. Unfortunately that's when my problems
started. My PC got stuck in a loop and just kept restarting.
I restarted in SAFE MODE and removed this software from the registry,
but now when I log on to my home page and try to do anything further
I get the following message "LOOK UP KEY WAS NOT FOUND IN ANY ACTIVE ACTIVATION TEXT".
I have tried repairing my Windows XP installation, but cannot get past
this message. Any help would be appreciated.
