Presumably youâre running the full version of Endnote and not the trial version.
Did you happen to move your Endnote library (.enl) file to a different location on your computerâs hard drive? If so, did you also relocate the accompanying .DATA folder to the same location?
Or did you transfer your Endnote library from one computer to another computer? If so, did you follow the instructions given in the knowledge base article âEndNote: Moving, backing up, or transferring libraries to another computerâ at http://endnote.com/kb/82295
You can try recovering your library by following the instructions given in the knowledgebase article âEndNote: The proper process for recovering library filesâ at  http://endnote.com/kb/82291

Thank you so much , I found that the problem was in importing some Pdf files as attachements from untrusted sources , so by moving all contents in Pdf folder inside Mylibrary.data folder then bring back one by one I could have separated the those sub-floders caused the problem.
I plan on importing lots of PDFs from PubMed, which I wouldâve assumed was a trustworthy source. Â I also make some of my PDFs (presentation handouts, notes, etc that I like) could these be marked as untrustworthy and cause this ridiculous error? Â If so how can I turn this feature off?
I have never heard of such a thing. Â I think it is far more likely a PDF is corrupted somehow. Â Have you tried the tool recover corrupt library? Â Before doing that, you might want to make a copy of the .enl file and the .DATA folder to a new location (not deep in the folder tree). Â Are your PDF names very long? Â â I would actually make the copy to a drive rather than the desktop or deep in mydocuments, for example. Â then try the tool on the copy. Â If you get it open, you might try copying all the records to a new library, which might leave corrupted files behind. Â Or if that glitches. Â copy 1/2 of them - if one of the 1/2s glitches, then 1/4 of the 1/2 that glitches, etc etc until you narrow down the offending record with the problematic PDF. Â
