Endnote can not add the FOUND reference

Dear All,

When i search a reference by its PMID number, the endnote finds the reference (at least it is saying that “Found 1 reference”) however when i click OKAY to add this reference it doent add the reference to the window. Yesterday was working fine. I couldnt solve the problem.

Appreciate your help

That’s probably due to an issue at NCBI and it has been fixed already. Zotero had the same issue – cf. Zotero not working in PubMed Central - Zotero Forums
