EndNote has been working well for me until today. I have it installed on my iMac and my Macbook Air. I keep my library synced on both computers using Dropbox.
Today, on both computers when I try to open EndNote, I get the logo box for a couple seconds, then it goes away and nothing opens. If I click on the specific library to open, it gives me a box with the error icon (triangle with exclamation point) and says "the document “My Library.enl” could not be opened.
