Why would you do that ? I bought the damn thing back when it was version 4 and I started using it because it's awesome. Now I have switched to windows and I can't use my old 1password 4 license bought for the mac and I can't upgrade.
That was a nasty move to get me hooked to this software, which I give you it's the best in it's class, but now I have to pay some 64$ to get a new license for something I already bought to use on windows.
