I am facing several troubles:
1.- I cannot open "Preferences" menu in my Windows 1Password App
2.- The backup directoy in my PC shows the last backup dated in october 2013, so I do not have any recent backup (December 2013)
3.- My dropbox copy is not updated. (1Password.html dated October 2013)
4.- I cannot open 1Password using firefox explorer.
I can figure it out some ideas to try, but rather ask you and wait for your recomendations to fix all this!
