NIS2011 AntiSpam not compatible with Outlook2010

I just upgraded from NIS2010 to NIS2011 using the check for update feature.  Everything seems to have upgraded properly except that I now get the following error message whenever I try to create a new message in Outlook2010:

 

8636i7B7656F3FDA24FC7

 

I did not have this problem with NIS2010.  I have tried uninstalling/reinstalling all of my MS Office 2010 Pro applications.  I have also tried uninstalling and reinstalling NIS2011.  I have tried using the Norton Removal Tool and reinstalling NIS2011, but the error persists.

 

I tried permanently turning off AntiSpam in the NIS Network Settings, but then I also receive the following error message when Outllook2010 starts:

 

8650iC2EE003FA8B1266B

 

This is then followed by the following error message when the Outlook2010 window opens:

 

8652iBE5023AF374C5CEF

I can halt the errors messages by disabling the AntiSpam COM Add-In within the Options settings for Outlook2010, but of course that also fully disables AntiSpam. 

 

I can uninstall NIS2011 and reinstall NIS2010 and the problem also goes away.

 

 

My system configuration is as follows:
  Pentium4
  2GB Memory
  Windows 7 Pro - 32bit.

  Office Professional Plus - 32Bit

  Visio Professional 2010 - 32Bit

  Project Professional 2010 - 32Bit

 

Hopefully you'll resolve this issue soon...
