Hello Juan,
Many thanks for the interest in Hauptwerk.
Please try:
- Make sure that you're logged onto OS X with an account that has administrator privileges.
- Make sure that all currently-available OS X updates have been installed.
- Make sure that Hauptwerk isn't running.
- Try re-installing the SafeNet/Sentinel driver by downloading and running the following installer (for OS X): http://downloadhauptwerk.com/drivers/Se ... lerOSX.dmg
- Follow the instructions in the installer to complete the installation. When it's complete, re-boot the computer, then see whether that's fixed the problem.
If not, is the clock in your Mac approximately correct?
