Endnote cannot open my library!

Help!  

I have been using Endnote X2 on my Mac for several months, and have built a fairly substantial library (but alas, did not back it up).

When I tried to open the library today, I received the following error message:  “The document “[library name]” could not be opened”.  Does anyone have any ideas as to what might be wrong – and how I might fix it?

Thanks in advance!

I am having this same problem.

I am running Endnote X3 on Mac OS X 10.5.8 and have been using Endnote for about 4 months now and all of the sudden I cannot open my library. I have not moved any of my library folders associated with the .enl file. I also tried double clicking it in finder, opening it within Endnote and still no luck. I tried importing a source from a database online and it says could not open ______. The blank being the name of the file of the source. The only thing that I can think of that I changed was the format Bibliography in Word from Annals of the Association of the American Geographer to Geology, but as I changed it back I am still having this problem. My .enl file is 287kb, is there perhaps a 300kb limit?

I just got a new computer, downloaded Endnote X4, then transferred an existing endnote library.  It won’t open it or rather says there are no entried.  I double checked on old computer, looked at the transferred files and they do not differ.  How do I make it read the files?
