Error Importing from EndNote

Whenever I try to use the Endnote Template under Education to import to DT3, I can import two citations but when DT3 tries to import the third I get an error similar to this. Any idea why?

What version of Endnote and is the Endnote window in the same space as DEVONthink?

Endnote version as below.

Yes, it is in the same space as DT3. I saw the discussion in the Forum in years past that the template will not work if different spaces are used - and indeed if I use two different spaces then I get a completely different error.

@BLUEFROG - Any further thoughts on this?
