problem solved !!!!
I have 1password in my laptop (Windows Vista 64 bits) and works perfect. Then, I bought 1password pro for my ipad. Now I can`t synchronize my data from my laptop in my Ipad. When I open the folder 1password in my dropbox and then I select 1password.html I get this error: "problem loading 1Password data file". I don´t use Crome, I use Firefox in my laptop.
What am I doing wrong? what I can do?
