I just purchased Coffee Cup Editor which I used previously as a trial version. Now when I try to save my work on top (or as) a previous web page, I get the message, "Can't create file..." I'm stuck, can't make a new web page.

Can you please explain a bit further what you have done? What are you trying to save on top of, and if it is a file from your trial version, is that file still open? What happens if you try saving it with a different file name?

Did you uninstall the previous version first? Did you install to default location?
