Fragen und Antworten zum neXt » Licence Issue after update

Hello,
some months ago I change my graphic card on my fixe PC. Until now without any problem with Next. I was running an old release (1.440), I don't know why but the auto update was not working. Yesterday I decided to install the last Next release. But now I get an error 8 : too many instalations. (I have also 1 instalation on my laptop). It seems that the touch "o" don't help me. Now I'm in demo mode ;o(
I tried the on ligne activation but it run endless with message data treatment.
Please can you help me. I afraid that even if I re-install my old graphic card I cannot solve this issue and on top of it'll be a mess.
best regards
Laurent
