I hope you don't mind, but I've moved your message to our 1Password 3 for Mac forums, in case you need more help with this. I'm sorry you're having trouble downloading the update for 3.8.22!
I'm not sure why that isn't working, but you can download version 3.8.22 from the "Legacy" section at the bottom of our download site. Then unzip the file (if necessary) and move the new app to Applications, replacing the previous version.
I hope that helps, but if you need anything else, please let us know. We're here for you!
