Online Mode of Endnote does not work

Hi, I am trying to search papers in the Pubmed database in the online mode of Endnote, when I type the keywords Endnote shows me a small window with the number of papers matching this keyword but after I press OK the program does not display the list of papers.

Can someone help me?

Thanks!
