Endnote X5 begins citations with 1

Hello,

I´ve got an problem. Yesterday I started citations with EndnoteX5 an OpenOffice 4.1. Yesterday evrything was right.

But today, when I´m starting to work with the same article, EndnoteX5 deleted all references of yesterday an started again with Number one.

I hope anyone can help me. :smiley:

Thank you.
