hyperlink reference not valid

Some of my references in my bibliography do not show the URL, instead they display "Error! Hyperlink reference not valid..  The interesting thing is that it is not all - just two, which use the same URL.  When I manually type the exact URL into a web browser the page appears.  I am using EndNote X6 and Word 2010.  Is anyone experiencing the same issue and have a suggestion?

Thanks.

Have you tried copying the URL direcly from the browser and pasting it into the EndNote records’ URL field? 

Thank you!!!  Such an easy fix.

I am having this problem as well. The above answer did not help me. I copied and pasted the url from the web browser and the same thing happens… Does anyone have another suggestion?

version of word, version of endnote what output style?
