Anonymous ftp returns message "unretrievable"

When someone uses Anonymous FTP to download publically available files, they get an "unretrievable" error message. I can't find any problems with permissions, and a named user can download files. This worked well before the update from 9. Any suggestions?

THANKS!!

I forgot to mention that there are no errors in the logs.
