After deleting a project from the Project Manager, if you then attempt to create a New Project, you will not see the proper families listed as target device families. For example, 4000XL and 4000EX will not be listed (although they should be), and 2000 and 3000 are listed (when they shouldn't be).
The problem is due to a bug in the Foundation Project Manager which is a result of deleting the currently open project. To resolve the problem, simply open up any existing project, and then once again attempt to create the new project. By loading the Project Manager with a known project, it returns to its proper operation.
1. Open any example design from the <ACTIVE>\PROJECTS directory.
2. Create the new project by selecting File -> New and all of the families should now be available.
