Find Reference Updates not working on a Macbook

A colleague doing a PhD has used Find Reference Updates across all 1500 references in his Library.

It did so for about 200 references and continually “egg-timed”, but still had not done anymore over a few hours. An error message appears now that says ‘The library is being used by someone else. Try again later’, even though the Library is not open elsewhere, and he now can no longer open the Library at all.

Any assistance would be appreciated.
