Was your Captivate 4 an upgrade? I ask because you mentioned that you uninstalled version 3.
I suppose it will help to know if Captivate simply works before attempting to troubleshoot an existing project. So I'd suggest you first test to ensure that you are able to create and save a very basic and simple project. Once you know whether that's working as expected, then you should dig deeper.
Layers... Ogres are like onions. With layers... End of story!
Well, I can't get 4.0 to allow me to open or create a new project, so you're right - that aspect is down as well. Tthank you very much!! BB
