Hi Umberto,
have you changed your profile password recently? If yes, please try to re-start the articy:server in case the change was not properly distributed into the password file of the subversion server.
If that does not help, please send me the articy*.log file from a your profile folder. This folder can be reached by pasting
%appdata%\nevigo\articy\2.x\logsinto the address bar of windows explorer.
Please send those files to
support@nevigo.com because those files contain your license key and this information should not be available to the public here in the forum.
