When I start MS Outlook 2007 I receive the following:

The Add-in "Spam Blocker for MS
outlook"(C:\PROGRA~1\SPAMBL~1\Bin\484~1.0\SBOLExt. dll) cannot be loaded and
has been disabled by Outlook. Please contact the Add-in manufacturer for an
update. If no update is available, please uninstall the Add-in. What does
this mean?
