Endnote library is not Saving properly-just lost 4 hours of work

Hi

I have Endnote X6. I just lost 4 hours of work because the library was not autosaving. I have started working again on the library but when I try to save, all I am able to do is save a copy, and when I look at the date/time tag in the directory, it is not updated even after I have made a change in the library and saved a copy. I am so upset and have no idea what is wrong. I have already rebooted.

Please please help.

Thank you.

Are the ‘Save’ and ‘Save As’ commands greyed out? I have this too and I’m not sure how I’m supposed to save it or if it’s supposed to automatically save as additional references are added.
