I'm having some trouble using my 1Password.agilekeychain with a new computer. This happened to me the last time I added a new computer.
It's a Mac running 10.6.7 using Dropbox to sync.
The keychain is in my Dropbox and works fine with two of my other computers. When I try to use it with the new system, I get one of three different error messages.
NSGenericException: Attempt to lock /Volumes/paul/Dropbox/App Support/1Password/1Password.agilekeychain/.lock failed unexpectedly
AGDatabaseError: The encryption keys file does not exist at 'file://localhost/Users/paul/Dropbox/App Support/1Password/1Password.agilekeychain/data/default/1password.keys'
Invalid Data File
Data File 'file://localhost/Users/paul/Dropbox/App Support/1Password/1Password.agilekeychain/' is incorrect or damaged. Please choose another file.
I have tried setting the path in the 1P prefs. I tried setting it using the "Find Existing" on the welcome screen. And I even tried double clicking the keychain, but nothing seems to work.
