"An error occurred while saving the configuration. Please make sure that you have permissions to change settings." I took the plunge, and upgraded from Nod32 2.7, to version 4. When I try and make changes to any of the setup options, I get the above error message. I am the only account on my computer. I log-on to Windows XP using a password. How do I get the necessary "permissions" to change settings? Thanks.
