When you imported the license file, you get a message: "Warning: This license file is incomplete! Do not use it as a backup"
For this reason it is not possible to make a backup through ArisAdmin?
 When I want to backup with:
%ARISADM_CMD% -l %BACKUPDIR%\arisbackup.log -t default -s %ARISSERVER% -u %ARISUSER% %ARISPASSWORD% backup all %BACKUPDIR%

"It is impossible to connect to ARIS Connect Server or ARIS Design Server. Use the ´server´ command to establish the connection or check if you have an appropriate server license"

Thanks!
