I've been using 1Password on my Mac since it's inception so I'm very familiar with it...and I also use it on my iOS devices. Today, I downloaded the Windows trial version to try on a Windows 8 laptop I have for business purposes. When opening 1Password (Windows) for the first time it asks if I want to "Open existing 1Password data", but clicking on that is expecting a pointer to my keychain on my machine somewhere. I want to the 1Password data in my Dropbox account. How do I do this upon initial startup of 1Password for Windows? Thanks.
