You might want to check the
AmithlonOpen mailing list. Look for the thread about
"A little good news" and also about building a new
bigird.gz. You might also want to look at the archives in the
Files section of that group, and also at
Amithlon_CD.lha in the
docs/help directory of your local Aminet archive.
Technical questions like this are better asked in the mailing list than in forums. You've got a better chance of an answer.
