Hello student,
The original trial for this (and other certain encrypted trial instruments) wouldn't have allowed you to load them in Hauptwerk v. 4.0.0. We changed how some settings for security worked for Hauptwerk 4.1.0 which did in fact allow these trial instruments to load, however due to issues with those new settings (due to Safenet/Sentinel software and driver issues) we had to remove that for Hauptwerk 4.1.1 and thus now you wouldn't be able to load trial instruments that originally required the owning of a Hauptwerk license to operate. (Technically it is now the same as it was for Hauptwerk 4.0.0 which also wouldn't have allowed you to load this trial instrument).
If sample producers create new trial instruments using Hauptwerk 4.1.1 then you would be able to try it without a Hauptwerk license if they update their previously released instruments by re-encrypting the files.
Sorry for any inconvenience that may cause you.
