Ok now I'm confused...
Your 1st post said "Color Navigator 7 cannot calibrate my CG210 any more", which to me meant that you were using CN7 before but then something changed and now it doesn't work anymore.
If that's not actually the case, then what were you using before if it wasn't CN7?
I apologize for confusing you.
I meant the latest version of CN, V7, doesn't support the CG210. The monitor was used by someone else for a while, and now I recovered it I wanted to calibrate it, looked on line, found ColorNavigator. My favorite software, namely Basiccolor is not available any more, and I never liked using i1Profiler for displays.
I have had no use for screen calibration on a daily basis because I do all my stuff on a 16" Macbook Pro, and the screen/print matches are usually good enough for my purposes. Before that I didn't print for about ten years.
The monitor was calibrated a long time ago by means of Basicccolor.
I guess one solution, after reading this thread, is to simply see if Basiccolor is still on an old machine and use it, and copy the profile.
