Can't add drawings to Print Organizer

I'm getting an error when trying to add drawings to a Print Organizer file.  I'm finding that it's doing it for both existing and new Print Organizer files.

There was no endpoint listening at net.pipe://localhost/[redacted] that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.

Any help would be greatly appreciated!!!
