F.M.

Thank you, some of the above responses helped me when I ran into the same issue today. It is worth noting that an update via the App Store also resolves this now, and a direct download from the website does not appear to be necessary. Additionally, the responses chastising those who were taken aback by the unexpected error and inability to login - despite having allowed the usual updates and being unaware that uninstallation and installation of a completely new version was expected - are not especially helpful. I also needed to resolve something time-sensitive, and had to make a plan by accessing a document on another device, then sharing it to my Macbook, while resolving this issue, and can relate to the frustration expressed by others. The attempts to defend hardworking EN employees are noted, but don't necessarily make others' frustrations less valid. Thank you.
