It seems that send-pr is not installed with your unique submitter-id.
You need to run

          install-sid YOUR-SID

where YOUR-SID is the identification code you received with `send-pr'.
`send-pr' will automatically insert this value into the template field
`>Submitter-Id'.  If you've downloaded `send-pr' from the Net, use `net'
for this value.  If you do not know your id, run `send-pr --request-id' to 
get one from your support site.
