Norton AntiSpam window keeps coming up

Hi,

Norton Security with Backup 22.5.2.15
Windows 7 Pro 32 bit
Outlook 2010

Problem: Welcome to Norton AntiSpam popup window won't go away

Every time I open Outlook 2010, the "Welcome to Norton AntiSpam" window pops up. Every single time I open Outlook

This despite the fact that "Don't show this again" is checked.

Possible cause:
The first time that Outlook was started after NS was installed, an Outlook Invalid Password box came up. I had to cancel and locate the correct password.

Even so, the next time when I entered and saved the correct email password, and the time after that, and after that, the AntiSpam window should have stopped coming up. But it still does.

How do I stop the Welcome to Norton Antispam window from coming up every time I start Outlook?

Thanks.
