Thanks Lusil for your response. I've had Dropbox installed on my iMac, Macbook and iphone for may years - i recently trialed TEAM DROPBOX for a month (Jan 3rd - Feb 4th 2019) but did not continue with the subscription - I believe this is when my problems started. I don't have any problems with Dropox syncing to my phone or Macbook. However, Dropbox seems to have stopped syncing to my iMac. The icon at the top of my computer screen has disappeared - I've downloaded Dropbox Installer again to try and get it back - it appears to download - i get as asked to sign in - i get sent an security code to my phone - then the error message appears -i've clicked "try again" - nothing happens and the error appears again - pressing "cancel" does nothing. It looks like Dropbox is trying to install (seen screenshot 3) but then it disappears completely. I've repeated this process several times. I still have access to my older Dropbox files on my iMac, but nothing new i create from my Macbook is syncing over. Please help!
