[Koha] Bulk Import Marc Records

Hi All, I successfully installed Koha 2.2.9 on a Debian Etch machince with Perl 5.008008, Mysql 5.0.32, and Apache2. Now I'm trying to bulk import some Marc records from winnebago. But I'm getting this error - Arguments must be MARC::Field object at /usr/local/koha/intranet/modules/C4/Biblio.pm line 1440. I found a thread about missing 090 fields. I used MarcEdit to add this field to the Marc records but I still get this error. I installed Marc-record, Marc-charset, Marc-lint, and Marc-xml for the cvs at sourceforge according to the Installing Koha on Debian Sarge how to on the kohadocs website. What I'm I doing wrong? Thanks in advance for any help, Mike
