mac endnote X7 not connecting with pubmed nlm

Dear All

I just found that my Mac EndNote6.0.2 isn’t connecting to pubmed correctly. 

When I search with a term that surely will produce some results, it gave error message “no reference was found” while library of congress or other database seem to be fine. 

Any insights on why this is happening? I never had trouble searching pubmed in EndNote before. Is the server down? or the linking address was changed?

many thanks for your comments and insights

Yes, I met the same problem yesterday, still the same now. I guess the corresponding database is down?
