I'm unable to load *.gsm files into Archicad 19 without a password. My Modlar password doesn't work.

Hi Richard,
Most of our objects are password protected to avoid errors when the user tries to directly open the object file. You can load object into the project library and use it in the project normally without opening it. You can change the settings through the object interface settings as well. Please let me know if you are still having issues.
