Friends are running AOL 7.0 on a Gateway 500S with Windows xp Home Edition, Norton Antivirus 2002 and Zone Alarm Pro. Recently they have been unable to start AOL or retrieve email. NAV has the latest virus definitions and ZL explicitly permits AOL an internet connection. Task Manager does not register AOL as running. The internet connection is via a Comcast cable modem. Downloaded and tried upgrading to AOL 8.0 which midpoint through the process decided that we terminated the install. All other software applications and hardware function normally. Thanks in advance for your suggestions.
