EndNote X.02 gives error message when I try to edit citation (Word 2007, Vista 32)

Hello,

Recently I’ve started receive error message that is “The parameter is incorrect” when I try to edit citation. I use Word 2007 and Vista 32 OS, if it’s relevant.

I can exclude author with great hindrance. At least I receive error message three times and try to do same thing three times. But somehow it works. However, adding page number doesn’t work at all. After few unsuccessful attempts I added page numbers manually and it worked. But page numbers were reformatted (deleted) when I tried to exclude author of another citation. I don’t know if the problem was existed before or not, since I’ve just started to use Endnote X.02 and Word 2007 combination recently and their combination gave me enough headache already. I really appreciate reply.
