I didn't reset nightly version

sosoapprehensive​ 

I'm sorry that you don't see the emails, is there a different email address that you could use to send an email to our team? 

That being said, let's see if we can resolve this here in the community. Can you try these steps: 

1. Log in to your 1Password account on 1Password.com (in the browser, not the app). Make sure that you see all of your items here and that you're signed into at least one other device.

2. Download and save your Emergency Kit.

3. Open the Start Menu, paste the following code into the search field, and press Enter:
   %LOCALAPPDATA%\1Password
4. In the Explorer window that appears, right-click 1password.sqlite, click rename, and change the filename to 1password-old.sqlite

Then try to open 1Password again. Do you see the same "Your saved data appears to be newer than this version of 1Password can use." error message or does 1Password open successfully?

Firstly, thanks, Chris, for the reply.

I have sent at least two e-mail messages without a reply.

I use, extensively, RFC 5233 sub-addressing with respect to e-mailing.  I have had mixed success with various websites and mobile apps understanding the 'plus' part of the address.  Perhaps the 1Password server is one that doesn't know what to do with mine.

One of the problems is that, using Outlook, I cannot send an e-mail message with the detail part appended to the local part. The latest version of Outlook (desktop) allows me to use the Reply-to field to designate the address that is actually my account identifier.

Is the e-mail server rejecting my incoming?  

I have a different e-mail address associated with my 1Password account than the one associated with my 1Password support account. Could that be an issue? Let me know if you need each of those addresses.

Incidentally, I did receive the notification e-mail in my inbox that was your reply to my post.

Regards, 

Chuck
