Using Zotero in Word 2007 after creating the original data in Word 2003

Hello,

I have following problem with my zotero:
I have gathered my library and cited these data in a Word 2003-document (Windows XP). Now I had to replace these settings by a new configuration to Word 2007 / Windows 7. I hadn't problems with implementing my old library into firefox, but in my dissertation-document zotero seems not to detect a link to the library. The attempt of editing or create new citations leads to the error-message: "Dieser Eintrag existiert nicht mehr in ihrer Zotero-Datenbank. Wollen sie einen anderen Eintrag als Ersatz auswählen." (This entry doesn't exist in your zotero-library. Do you want to choose another entry as an alternative?)
Cause I am not really in the mood to search and insert again all of the citations, is there any possibility to help me with this problem?

Thank you very much,
Phil
