Help! all refs dissapeared!

Hi, i’m using endnote web and suddenly all my references are gone, all 5000+ of them, and all is left are the folders with (0) by them. And when i try collecting a new ref online it still stays at 0. 

When searching for refs in word it just comes up with “no such item” type message.

How can i fix it?

Thanks!, eva
