MS Word trouble with Zotero

So, finally I decided to go with MS Word. I was satisfied with improved equation editor and expanded spread sheet. But I faced annoying trouble of MS Word: I consistently get error message when I try to edit bibliography, which Zotero produced, at MS Word document. The error message says:

Run-time error '91'
Object variable or With block variable not set

It is a well known problem at Zotero forum. I searched the forum, and I tried every single solution. But there was no cure for my case. Zotero forum also says that the cause of the error is unknown in many cases. I had no problem to edit my bibliography at Open Office, which I miss already. Finally, I gave up. I would rather edit my bibliography without Zotero field. Someone suggested to use JabRef which uses BibTeX, but I don't have much time to fiddle with new application...

By the way, I tested the problem at MS Word 2003 at a different computer. I got the same error message. Something wrong at the relationship between MS Word and Zotero. I bet Zotero hates MS Word. Or, vice versa.
