Update Reference in X5

No matter what I try update reference returns the same error message:

We were unable to find a reliable match for this record.

I’ve tried dozens; same result.

is there some setting I need to tweak or does this feature just not work?

How were the refs entered in the first place.  This usually works if the record is imcomplete when you have downloaded it from a database and requires certain info, (usually the DOI I think).  If you just have authors and titles, that isn’t enough in the current rendition of the Endnote (x5) program.

Thanks. That would explain my problem.  Seems like misleading advertising not to mention this limitation.
