When I either manually type or select from the object browser the site I want to use with the process wizard, the wizard will not allow me to browse the lists & libraries in that site and shows an error "protocol not supported" - I'm sure that the site I've selected is a top level site as per the wizard help instructions,and I can browse all the site objects in the object browser, it just seems that the process wizartd refuses to work with any of my sites.

Hi Ismac 

Can you please give more details with regard to the site url you have specified? where is the server located and what is the exact url you are using?

did you get this working?
