OK, I have an even more basic question along the same lines. I ordered the program and they sent me an email, but the email includes the phrase "save attached file to any folder". Well, there's no file attached to the email they sent. I thought perhaps I misunderstood, and went into the wnsoft.com link that came with the email, and downloaded the program from there, wondering if the load key/registration box that the previous poster refers to would appear, but I seem to get an unregistered version of the program. When I run that file, I get a box that asks for a registration number, but when I cut and paste the load key into that box, I get an error message. I suspect that the unregistered trial version of the program is not what the previous poster is referring to. By the way, as mentioned, I have found the key in the email I received. I suspect that either there is a file that was stripped out during emailing; or else I am making some very basic conceptual or procedural error. (And it wouldn't be the first time, either. ) No response from wnsoft support as of yet. Any thoughts? Thanks.
