Because this program is used to control the bandwidth of the programs from your computer which access the Internet, you should always run it using Administrator rights. Also, the product might not be able to access the Internet because it is blocked by your system's firewall or the firewall from the third party antivirus application. To fix this issue, go under Start > Control Panel > Windows Firewall and add the program to the Allowed list. You should also do this for the antivirus program.
