I recently transfered all of my files from my old Mac to a new Mac. I am running EndNote X2, and when I opened it on my new computer I could open any of my old EndNote libraries except for the one I created most recently (which houses over 100 references I’ve created so far for my dissertation). When I try to open that library I get the message “The document [libraryname.enl] could not be opened.” But I have no problems openining any of the other various libraries on my computer.

I went back to my old computer and for some reason the library won’t open on that computer either (even though it was working fine 2 days ago). I pulled up a backed up copy of the library on my old computer that did not include the most recent changes (in case the most recent changes were what messed it up).&nbsp; But I still had the same problem - it won’t open.

I tried the “recover library” function in the tools menu but it didn’t work, since 0 citations were recovered.

Any idea what gives? Why on earth would this one library stop working when all the rest are just fine?
