Hi ant.anestis,
Please try and do a clean reinstallation of your eLCC:
==> Reboot your computer(!) an open the “Terminal” application which resides in “/Applications/Utilities/”
1) Copy and paste the following command into the Terminal window and hit the <Enter> key (this is one single line only):
sudo rm -rf /System/L*/E*/Auth*S*.plugin
After hitting the <Enter> key, you will be prompted for your administrator's password -- please enter it (although it will not be visible during typing) and hit the <Enter> key again.
2) Copy and paste following command into the Terminal window and hit the <Enter> key (again, this is one single line only):
sudo rm -rf /Lib*/Pref*/.Auth*S*
3) Copy and paste following command into the Terminal window and hit the <Enter> key (once more, this is one single line only):
sudo rm -rf /Lib*/App*Support/Syn*S*-eL*
Now, your eLicenser Control system is not in a functional state anymore, therefore, before launching any application etc.:
4) Install the latest version of the eLicenser Control from:
==> https://www.steinberg.net/en/company/technologies/elicenser.html
After successful installation, you will have acquired a "clean" eLicenser Control system.
Does that make a difference?
Best, Marnix
