Thanks nekrosoft13 fom our BPN Forum
This new version should solve all problems with the latest version of ProtectCD 5© used in Port Royale© Patch 1.3 together with the updated MDS-File for Port Royale you can download here. The updated MDS-File is already out for a few days and it seemed to work for most people but as VOB blacklisted DAEMON Tools in the latest ProtectCD 5© version we also needed to update DAEMON Tools again.
