Automator "Save-as plugin" not working

Hi, I am new to automator. I'm working on a Powerbook G4, in osx.4.11, and I'm trying to save a workflow as a plug-in in automator. When I click file>save as plug-in, nothing happens. I get no pop-up, and no plug-in is saved. I've tried this with various workflows.
I'm also having trouble adding actions to the workspace (even ones that make sense to add, i.e. I am following a tutorial to create a workflow that others have made before).
Any ideas of what the problem could be? Thanks

 

clarification

To add actions, I try double-clicking them or dragging them in, or using the "+" sign at the bottom, nothing works. It's like it's not responding at all.
