Problem with Pubmed/online searching

I don’t know what is going on, but I have always been able to search pubmed from the main window in Endnote, and any references I found were automatically put into the library.

Now, I have to go into the “online” tab and the references I pull up don’t go into my library and I can’t insert them into my document.

Help! I’m on a very tight deadline.

My problem is I always used the integrated library mode because the online search mode does not work. It searches for ages, and does not return any result. Why is that?
