My projects have been created using websiteX5 Professional 11.  I purchased websiteX5 Professional 12 and have my preferences pointing to the correct directory.  Within websiteX5 Professional 12 I click on an exisiting project in the "Edit an existing project" area  I receive the Error message.  "An error occured while loading the Project. Could not find file. "  The program is looking for a "library.xml" file.  There is probably something I missed reading.  Do I need to mirgrate the project some how before using it?   Do I need to do something with the project folder for that specific project before editing it in websiteX5 Professional 12?
