MyEndnote library on the Macbook has vanished, all I can find is a sample library with a completely different content. I also cannot find any .enl or .data file on my computer, and haven’t done any backup on the device 
Fortunately I have an Endnote online account and I had recently synced them both. So if I create on my desktop a new ‘MyEndnote library’ which is at first empty and I then sync it with my online account, will I then be able to re-import all my references (hopefully), or will the sync process wipe my online account out as well and nothing will be left ?
Thanks for your help !
