Let me Paste my Password
I tried your free engine or whatever you call it. Why have you created an application that won't let a user paste their password? My password is very complex, and I will not type it. I paste it from my password manager. For this reason alone, I will not look at your products again.
Sorry for the inconvenience, this sounds like a bug. Try right-clicking in the Password field and choosing Paste from the context menu.
