Endnote library missing

I used ENDNOTE 14 when I wrote my PhD thesis 2/3 years ago. I haven’t used Endnote since. When I opened my thesis Word document today I couldn’t access the Endnote library at all. It came up with 0 as the number of references. I have a saved copy of the libray on my PC  (an .enl file) but when I tried to open that I got the message ‘Could not convert the library to the latest format, becasue the libray is locked or is on a locked volume’. Please can anyone help!

did you move the .enl file?  What you need is the libraryname.DATA folder - not just the .enl file.
