Upgrade messed me up!

Welcome to the forum, @momneedshelp - and may I start by saying that if we had a contest for best forum name of the week/month/year/whatever, I'd be nominating you. :)

I'm also glad to see you being cautious when it comes to the valuable data you store in 1Password. On iOS, you would lose your data if you deleted the app. Fortunately, however, on the Mac, things work a bit differently. Your apps are stored in your Applications folder, but the actual data you create in 1Password (or other Mac App Store apps) is kept in ~/Library/Containers/... - so, in other words, you can feel free to delete and re-install 1Password without fear of losing your data. Not to worry. :)

To delete 1Password, just open your Applications folder and drag it to the trash. Don't use any app cleaners or uninstaller programs to do this, as these programs can remove more data than we want them to. Just drag the 1Password app to the Trash, then restart your Mac. When your Mac restarts, open the Mac App Store and visit the Purchased tab (along the top of the window). Search for 1Password and click "Install" to the right. 1Password should download and install. Return to the Applications folder and double-click 1Password to launch it. Everything should be good! Let us know how you get on.
