Jabref导出到Office 2007 xml失败

At first I am not 100 percent sure if this question belongs here, so may be I need to move it. Anyway, I have trouble exporting my bib file to an Office 2007 xml file using JabRaf 5.0. In the older versions of JabRef this was no problem, I used to do that all the time. Please see attached some screenshots whith the error. enter image description here
