[Koha] KOHA on windows install problem

Hi all I have a problem with our KOHA installation. I was wondering if anyone can point me in the right direction. On the catalog module of our Intranet, it shows the bib and item records but only the bib record is displayed on the OPAC and no copies (Non reservable) nis displayed. I also noticed on the server that on the intranet, Parameters:MARC Links:items, page is empty. It was working fine and all of a sudden it stopped working. The install details are as follows: windows server 2008 Koha version 2.2.9 Apache version 2.0 MySQL version 4.1 Active Perl version 5.8.8 build 820 Any help would be appreciated -- Regards M N Yakubu (0805 703 2980) American University of Nigeria Lamido Zubairu Way PMB 2250 Yola Adamawa state
