Import word bibliography to endnote

Hello everyone,

Before I began to use endnote (X3), I created a long list of bibliography by using word 2007 and all items are in the uniform format. Now I am trying to import these reference items to endnote but have no idea about how to achieve it. I have tried the tool menu “export to endnote” within Word but none of the three choices (i.e., “export traveling library”, “export word 2007 citations”, and “export word 2007 master list”) seems to work. I wonder if anyone knows how to conquer this?
