I'll let you know about the key tomorrow, I have to call about the upgrade for something so I'll ask. The upgrade page on the website specifically says you will get a new key for the new software and your Profiler Gold or Platinum key will still work with that software.
I'm a bit concerned about Andrew's comments regarding black generation in CMYK profiles, as noted in his review this is something that is absolutely needed, especially if you have something like a CMY K, lk, lllk (really extra light black) workflow which would allow a nice heavy black generation to be used in all areas. It is sounding like Colorport and Profiler will stay in my toolbox for as long as they will function, yes I'm one of those odd people who still like the Pulse hardware.
