Hi at Nitro,
Got a strange effect trying to activate Nitropdf Pro vs11, just like others who have reported this issue:
The License portal says: 2 activations, 0 activated; License is active.
Both my PC's say: --23 error; max. already used.
So I think you have to make a change in my config file, I assume. If you like I do have a schreenshot available.
Thanks in advance,
