When i try to open a v13.0.1.16 iwzip version of a project, it copies the project but then it won't open, with the error message Personal Site Migration (the name of the project) and "The specified Project cannot be opened because it was created with a later edition of WebSite X5 (Pro)."  When I try and open the copied/converted project, I get the error "An error occurred while loading the Project. [Exception of type 'WebsiteX5.BL.ProjectNotFoundException' was thrown.]"

Any ideas?

Thanks,

Richard
