In Outlook, whenever I open my Address Book, I get the error message "Invalid
class string" in a windo that has the heading "Error: Creating instance of
COM object". I click OK, then I get the same message in another window with
heading "spamBlocker Add-On Message". After clicking OK on this one, it
stops for a few seconds, then the process starts all over again. It does
this the entire time my Address Book is open.
