How to sync with EndNote Web

Thanks.

It doesn’t seem to recognise my EndNote Web account/password as the attached window keesp popping up.

Please advise.

ps. I have checked many times that my email / password have been entered correctly.  I have no trouble logging into the EndNote Web at all using same email and password.

pps. I have tried restarting my laptop several times too…

Any  advice would be appreciated.

Many thanks.
