Errors Encountered While Retrieving References
For various reasons, some references cause errors during retrieval. If EndNote encounters an error while retrieving references from an online source, it stops the retrieval process. In order to get the rest of the references, it is best to submit the search again, and this time request the references start downloading with the one after the reference which might have caused an error. For example, if the error appeared while the tenth reference out of fifty was being retrieved, submit the search again, and when prompted, ask only for references 11 through 50 to be retrieved.
EndNote typically retrieves references in batches, for speed and memory reasons. However, some servers are too slow, or their record data is too large, to support batch downloads. If you find that your connection with a service provider fails after approximately the same amount of data each time you attempt to download references, you can try turning off batch processing. You will need to open the connection file you are using, as described under Editing a Connection File, and deselect the Batch Download option described under The Connection Settings.
