Windows Mail - Problem with Contacts

• cannot access contacts from the To or Cc buttons - it says 'unable to choose recipients'
• cannot edit any contacts  -  a small window briefly flashes and goes away...can't even read what it says.
• cannot import or export contacts...I get an "OK" box with a red "X" in it...no message text
• can however:
• • start typing an email address in the To or Cc which will autocomplete
  • right click on a email address and have it Add to Contacts
  • see all contacts on the Contact directory via Windows Explorer
  • cliik on a listed contact, see the email address in the righ windows pane, click on the address and compose and email from there.
  • send and recieve mail

The Default programs correctly points to Windows Mail.

I had seen in some google searches that the KB933928 Windows update could be the problem...but I have it installed on my machine so I dont think thats the issue - also likely not a good idea to uninstall a Microsoft update..

Any suggesttion on how to fix this??
