Hi, I have migrated from Nod32 to Smart Security. On installation, I have used the new Username and Password to activate the product. I have had Smart Security on my computer for less than 24 hours, in which time, it has rejected both Username and Password on 4 occasions. Each time this occurs, I have to copy and paste this information - and reboot in order to become operational. As I type this, the Smart Security icon has again turned red in the notification area. Any suggestions?
