I have Endnote X2.0.1, running on Mac Snow Leopard (also with Word 2008). I cannot delete references from my library, using either trash (command or drag) or the delete button. I saw something in another thread regarding multiple problems, including this one, for which the answer was to reset the preferences. But I have modified an output style and created a number of specialist references types, so I would dearly love to avoid having to re-do all those. Anny suggestions?
If this is a Preferences issue on the Macintosh then it involves the “com…endnote.plist” file. This is separate from the “RefTypeTable.xml” file that includes details of your customized Reference Types. It should be possible to reset one without impacting the other.
It might be worth calling our Technical Support team - 800-336-4474- they are very knowledgeable and would be happy to walk you through the process.

This can also happen if the library is damaged. Using the recover library command on the library and then working with the recovered library should allow you to properly delete references:
