I don't have a problem with student versions having the watermark. The problem I have is that when I copy anything... a symbol, a section of a drawing... anything... from a watermarked file... I end up with the watermark for life AND... I can longer Export to PDF without this non-password password problem. And printing to PDF works only if you have days to wait for it to work. I light many shows when the set designer is an academic... it's a problem for me!
