I had a problem with my computer a couple of days ago, three days after downloading the pro version of NI. Can I download it again, as the remains of it on my computer no longer work, using the same info emailed to me the first time around?

Is there a preference when to use IN on scanned B&W negatives? I usually scan (Canon 4000 ppi film scanner) in positive RGB 14 bits per channel mode or 16 bit grayscale mode, also positive. Should I invert in PS before running NI or leave it as a negative? I assume if I want to build film profil...
