Innopac references into an EndNote Library

["F. Javier Maestrojuán" <maestro@xxxxxxxxxx>]

I'm using Innopac system at my University Library Catalog in Navarra (Spain)

 http://bibl-innopac.unav.es/

and I'm having troubles importing references into my EndNote Library. There is actually an EndNote export option in the library system  but it does not work well: it only exports author, title and Notes fields, which it completely useless.

The other export option I could choose is MARC, but I don't know what kind of marc filter should I select to import the references into EndNote. I've tried usmarc, melvyl, stanford, etc. with very bad results.

Could anybody help me?

Thanks a lot
