I cannot get the “SharewareOnSale exclusive license key” of ZTP8R-WDNJL-CRABF-Z9SHP-XH7JX to upgrade the program from the free version to the Pro version (on my Windows 7 computer).
Entering this license key and pressing the “Activate” button consistently returns the following error message (both on several attempts following installation, then on several attempts following a reboot):
“Xvirus Personal Firewall The remote server returned an error: (404) Not Found.”
