Error Number: 0x800CCC19 - Cannot use comodo email scanner

I am using Outlook Express and am unable to keep my email anti virus scanner checked. When I uncheck it - all messages come in fine and are sent. When the Comodo email scanner is checked on for incoming and outgoing emails - I get the following message: Error Number: 0x800CCC19

Any ideas of how I can protect my computer, but still rcv. and send emails???
