Editing, Deleting or Modifying points or devices in CIMPLICITY WORKBENCH

Hi everyone, i'm having trouble with a project in CIMPLICITY WORKBENCH, i can't edit, delete, modify points of an existing project. I'm logged as the administrator and i can't do any of those changes.

Is there a way to enable those options or am i missing something?

Thanks in advance for any help you could give me.

Hello,
actualy i'm having the same problem with cimplicity 5.0, i was able to edit on the workbench but in the last couple of days it is impossible to do so and i can't even get to the project properties.
have you guys found a solution for that?
