I didn't put this on the comment page because it seems that perhaps I am the only one with this question although I don't know why. The Zen writer installed fine and works really well only I have been all over it and can't find a single spot anywhere to enter the registration code.
There are comments about how copy and paste doesn't work to input the code so apparently people are having to do it. However, I haven't had to but am also not getting warning or trial messages either. I don't know if it will work tomorrow without entering something but I can't find anywhere I'm supposed to.
Perhaps this sinus infection is clouding my vision, I don't know. Thanks for whatever help you can give me.
