BITEARN NODES is checked against all major software packages, including
LISTSERV, LMail and MX, before it is released. It is done once by EARN
(Hans-Ulrich Giese), and then a second time by me to make sure no error
slips through. So when you get that kind of error, you can be 99% sure
that something is wrong with the file you obtained. Try to get a fresh
copy and run the table generation again.
